1.0 Product Introduction

The RD-30 Portable Three-phase Electricity Standard utilizes a lightweight, compact package while providing a high level of accuracy through design innovations. The RD-30 has a typical accuracy of 0.01% and a maximum worst case accuracy specification of 0.04%. This specification includes variables of stability, temperature, power factor, traceability uncertainty, and test system errors. In addition, this accuracy applies across the entire voltage and current operating range of the product for an entire year.

The RD-30 utilizes Radian’s new Dytronic measurement technology consisting of a Radian designed Integrating Analog to Digital Signal Converter. The RD-30’s Dytronic A/D Converter is combined with Radian’s renowned electronically compensated voltage and current input transformers and a hermetically sealed reference set to provide the highest degree of accuracy, stability and versatility offered in a portable three-phase electricity standard.

The RD-30 provides four quadrant three-phase simultaneous measurements for active, reactive, and apparent energy and power with forward and reverse energy flow also measured. The potential input, current input and auxiliary power input are totally autoranging. This autoranging feature was pioneered by Radian Research and makes it impossible to damage the unit by applying a signal to the wrong tap. The potential input range is 30 to 630 volts, the current input range is available as either 120 amps or 200 amps per phase. The auxiliary power ranges from 60 to 630 volts.

In the field, the RD-30 can be used with a controlled current load, or it can be used with clamp-on current transformers available from Radian Research to perform customer load tests. In this field application, the optional power analysis capability can analyze customer load through the 204th harmonic order. In addition, for improved efficiency, the RD-30 optionally can automatically calculate and display the error of the meter under test.

The RD-30 also provides a serial communications port which allows direct connection to the RS-232 serial port of a personal computer. RD-30s with the Built-in Computer option come with RR-MobileSuite software.

The RD-30 is available in a variety of models offering measurement functions and options to suit specific needs.

1.1 EnhancedDesignFeaturesMany design features have been added or improved through the engineering process of designing the RD-30 Dytronic. The addition of A/D and DSP technology, increased PC support and an enhanced version of Radian’s revolutionary voltage and current transformer input design make the RD-30 the benchmark of portable standards, second only to the RD-31 portable threephase reference standard. The RD-30 utilizes Radian Research designed Analog/Digital circuitry coupled with Digital Signal Processing techniques. These advancements provide a high degree of flexibility including simultaneous multifunction measurements and harmonics analysis capabilities.

A/DandDSPTechnologyIn order to accelerate the testing process, Radian Research has designed and incorporated a custom integrating Analog to Digital Converter into the RD-30. There are separate A/D circuits for both the voltage and current axes. Couple this enhancement with the utilization of DSP technology and the RD-30’s abilities are greatly enhanced. The RD-30 can effortlessly collect the converted digital signals from the A/D converters and process the data to display every measurement function supported during a single collection of voltage and current data.

PCSupportFor enhanced analysis and testing, each RD-30 is equipped with a communications port. This port will allow the user to connect to a personal computer running Radian Research software packages providing for customization of the standard. Different configurations containing input and output port designations, LCD menu operation and other parameters may be stored in RR-PCSuite software and downloaded to any RD-30 unit for complete user customization.

In addition, the RD-30 can analyze harmonic distortion complete with each order’s phase and amplitude. This information can be studied in the laboratory with Radian software for a more complete understanding of conditions at specific meter installations. Additionally, voltage and current waveforms can be viewed in real-time and then captured for later investigation. Test results of both revenue billing meters and field standards can be stored enabling complete and detailed histories to be recorded.

ClampOnCurrentTransformerInputThe RD-30 features a clamp-on current transformer input per phase. This option allows true customer load testing without removing the meter from service.

VoltageInputs,CurrentInputs,AuxiliaryPowerInputsThe RD-30 provides full autoranging capability for the Potential Input, Auxiliary Power Input and Current Input using electronically compensated input transformers designed by Radian. The voltage and current inputs contain an enhanced design of Radian’s original electronically compensated transformer. This feature ensures the unit will never be damaged by applying a signal to the incorrect input. Current input options are 120 amps maximum per phase or 200 amps maximum per phase direct connection.

With the safety of the user in mind, the connections have been updated to an insulated socket design. The Potential Input and Auxiliary Power are 4mm connections and the Current Inputs are 6mm connections for the 120 amp model and bolt-on current connections for the 200 amp model.

1.2 LaboratoryApplicationsThe accuracy and precision provided by the RD-30 allows it to easily test portable field standards of lesser accuracy. The optional built-in comparator allows for automatic test result calculations for the field standard being tested.

1.3 TestTableApplicationsDue to its small package size, the RD-30 can easily be used as the reference within test tables whenever a higher level of accuracy is desired. Programmable pulse outputs coupled with an RS-232 communications port make it easy to receive data from the RD-30.

1.4 FieldTestingApplicationsWith a weight of only 6.81 kg (15 pounds), the RD-30 is conducive to field-testing applications where a high level of accuracy is desired. The optional built-in comparator allows for automatic test result calculations of the meter being tested.

1.5 PowerAnalysisUnlike off-the-shelf A/D Converters used in other instruments, Radian’s Dytronic A/D Converter is specifically designed and optimized for power and energy measurement. This unique design allows the RD-30 to accurately measure non- sinusoidal waveforms up to and including the 204th harmonic order. Measurement parameters include the phase and amplitude of each harmonic as well as the total harmonic distortion. The unprecedented accuracy of measuring distorted waveforms combines with this optional powerc analysis capability to clearly distinguish the RD-30 as the definitive portable three-phase electricity standard for both meter testing and power quality applications. This power analysis option is also useful when testing meters using customer load.

1.6 CustomerLoadTestingFor those applications where meter testing with customer load is desired, the RD-30 is an obvious choice because of its ability to accurately measure energy and power even with distorted waveforms. The optional clamp-on current transformer inputs on each phase allows for testing the meter using customer load without the need of interrupting service.

1.7 AutomaticCalculationsOptionally, The RD-30 offers a Built-in Computer for two types of applications. For laboratory applications, the Built-in Computer can accept output pulses from a portable field standard and automatically calculate and display the error. For field- testing applications, it can also automatically calculate and display the error of the meter under test. In this field-testing application, various sensors (for disk rotation, infrared calibration pulses, KYZ pulses, etc.) may be connected directly to the RD-30 and parameters for the test may be easily entered. At the conclusion of the test, the results are automatically calculated and displayed on the LCD. Optional sensors include the RD-DS Meter Disk Sensor, RD-1H Infrared Optical Pickup, RD-1H/v Visible Optical Pickup, and RD-KYZ Pulse Input Adapter.

1.8 SoftwarePackagesThe RD-30 also provides a serial communications port which allows direct connection to the RS-232 serial port of a personal computer. In addition, Radian offers software packages to suit various applications.

RR-PCSuite software allows for custom configuration of the RD-30 standard. This custom configuration includes defining scrolling sequences, scrolling times, defining communication ports including output pulse values, defining measurement displays, and other operation parameters.

RR-MobileSuite software is used with the power analyzer functionality of the RD-30. RR-MobileSuite provides the ability to view current and voltage waveforms in real time while providing total harmonic distortion as well as analysis of harmonic order, phase and amplitude. Waveforms may be saved for further analysis back at the meter laboratory.

Operations Overview

4.0 Operations Overview

4.1 MeasurementPrincipleThe measurement principle is based upon the fundamentals of a high-speed charge-balance integrating analog to digital signal converter. This is a Radian innovation, but it is based upon accepted metrology parameters. Radian Research implemented its own analog to digital converter in the Dytronic family of standards which are specifically designed for power measurement. In order to measure power and energy with extreme accuracy and wide bandwidth, extensive requirements must be imposed on the converter.

The RD-30 Dytronic utilizes two separate A/D converters. One accepts a current signal and is linked with two current references. The other accepts a voltage signal and is linked with two voltage references. These of course are for the analog voltage and current inputs of the RD-30. Both operate independently to provide the digital signal processor with signals accurate enough to meet the requirements of a true portable electricity standard.

By designing an analog to digital converter specifically for power and energy measurements, Radian is able to reduce many errors associated with commercial A/D circuits. Gain error, charge timer resolution, signal to noise ratio and signal distortion were major areas dealt with and improved in development.

4.2 InternalReferenceSetThe RD-30’s internal reference set is hermetically sealed in order to protect it from environmental variables. The internal reference set consists of a voltage reference, a resistive reference and a crystal time reference.

4.3 OutputStageThe RD-30’s output stage displays the measurements and provides pulse outputs for the selected measurements. Computer control, with Radian software, allows for customization of output information, such as programmable pulse output constants.

4.4 VoltageandCurrentInputs*The voltage and current inputs are completely autoranging – a design feature that was pioneered by Radian Research with the RM-10 in 1985. The voltage and current inputs consist of a toroidal autoranging electronically compensated transformer. The Radian toroid transformer provides superior immunity to stray fields and the electronic compensation eliminates practically all of the transformer error.

4.5 AuxiliaryPowerInputsAuxiliary power is required to power the internal workings of the RD-30. It may be derived from the same signal as the potential input providing that there are sufficient volt-amperes available. Auxiliary power may also be supplied independent from the potential input source. The power supply for the RD-30 is a very advanced switching power supply which is inherently capable of converting the available input power to regulated power over the entire operating range. The con-verter is so effective at this that the input may be changed freely between the ranges of 60 and 630 VAC during operation without a measurable effect upon operation.

The connections have been updated to an insulated socket design. The Potential Input and Aux-iliary Power Input are 4mm connections and the Current Inputs are 6mm connections (bolt-on design for 200 amp models). It is now virtually impossible to touch any live connection while the unit is in operation.

4.6 Clamp-OnCTInputThe RD-30 features a clamp-on current transformer input. This input can only be utilized with Radian approved current transformers, as others do not have the inherent accuracy needed to optimize the RD-30’s accuracy and stability. The input is a seven-pin connector that provides power, serial communications, and an input for specific clamp-on current transformers.

4.7 PulseInputsThe RD-30 Pulse Inputs consist of BNC connectors labeled 1, 2, 3. These inputs are open collec-tor. Phase A input is labeled as 1, Phase B input is labeled as 2 and Phase C input is labeled as 3. While doing a meter test a RM-1S Remote Reset Switch may be connected to input 3 (Phase C input) and can be used to gate (start/stop/reset) all three inputs simultaneously. Or, instead of the RM-1S, any of the Radian pickups may be connected to input 3 (Phase C input). The pickups con-sist of the RM-1H, RM-DS, and RM-KYZ, all which can be used to test various electricity meters. While doing a standards test all three inputs can be used individually or simultaneously.

4.9 AnalogSenseInputThe optional Analog Sense functionality allows the RD-30 to effectively test transducers as well as first generation electronic meters that have an analog output for calibration. The RD-30 will not only test these instruments, but it will also automatically calculate and display the error.

4.8 PulseOutputsThe RD-30 Pulse Outputs consist of BNC connectors labeled 1, 2, 3. These outputs are open collector. The factory default setting is Output 1 = Total Watthours, Output 2 = Total VARhours, Output 3 = Total VAhours. However all three outputs are programmable by the customer for per phase energy or total energy.

4.10 SerialPortCommunicationsTerminalThe communications terminal is interfaced via a DB-9 connector. Through the use of this terminal, a myriad of capabilities present themselves. Not only can each RD-30 software package be utilized, the RD-30 can actually be re-calibrated through this terminal. Additionally, the flash memory storage for both the DSP and Xilinx programs is accessible through this terminal making the RD-30 field upgradable.

4.11 PickupTerminalThe sensor input terminal on the RD-30 comes in the form of a 4 Pin Lemo connector. Radian Disk sensors, infrared and visible LED optical pickups can be utilized to sense disk rotation or equivalent revolutions. See Section 2.1 Generating RD-30 Model Numbers for further information.

4.13 Built-inComputerFor RD-30s ordered with the Built-in Computer option, the display screen is a color active, QVGA LCD. The diagonal display size is 14.4 cm (5.7”). The display’s pixel format is 320 (H) x 240 (V) and the display is backlit with a single CCFT.

The RD-30 display incorporates “touch screen” technology that allows the user to easily ma-nipulate the display. The RD-30 is shipped with a stylus to be used in conjunction with the touch screen.

Guard– should be tied to the common of the Wye source for Wye usage and left to float in Delta use applications. Because the Analog Sense is common with the Guard ground, care must be taken to avoid ground loop problems.

V1,2,3/VN– the three VN connections should be tied together, via twisted wire pair, with their as-sociated Potential Inputs (V1, V2, V3). At the Device Under Test (DUT), each VN should be broken out from its associated twisted wire pair and each tied to the DUT Neutral with the three Potentials (V1, V2, V3) tied to the three Potential connections of the DUT. The three Potentials (V1, V2, V3) of the DUT should be tied to the associated three Potentials of the source. If using a Wye source, the Neutral from the DUT, containing the three VNs, should be tied to the Wye source neutral. If using a Delta source, the DUT Neutral, containing the three VNs, should be allowed to float.

Service & Routine Maintenance

25

5.0 Service & Routine Maintenance

The RD-30 Dytronic portable electricity Standard is virtually maintenance free. The elimination of all contacts, switches and tap selections on the primary side of the input transformers significantly improves reliability by eliminating both service components and the opportunity for operator error. Other than cleaning of the outside surface and the yearly recalibration, no routine maintenance is required.

5.1 CleaningCleaning of the RD-30 may be performed with a clean, dry lint-free cloth dampened slightly with a mild window cleaner. The areas around the top terminals should be buffed dry with another cloth, which is completely clean and totally dry.

5.2 RepairIt is recommended that Radian Research perform all repairs. We have excellent automated testers with which every internal module can be tested quickly to original factory specifications. A final calibration and quality control inspection to original factory specifications is performed quickly and thoroughly. If the RD-30 is in need of repair then contact Radian Research or your local Radian Research Representative and request a Return Material Authorization (RMA) number. You will need to provide the model number and serial number as well as a detailed description of the problem.

5.3 RecalibrationRecalibration is recommended yearly. A periodic cross check against a Radian RD-21 or RD-22 or RD-31 is recommended to preclude the possibility of a failure in either. Prudence would dictate having a dedicated RD-21 or RD-22 or RD-31 for cross check purposes. With the RD-21 or RD-22 or RD-31 it is feasible to sample test units at various points as a “backup” test. In addition, it is recommended that one take advantage of Radian’s recalibration service as a very cost effective method to maintain traceability Radian Research’s Calibration Laboratory maintains primary transfer standards that are directly traceable to NIST. Radian Research’s Calibration Laboratory also maintains several RS-703A Automated Calibration Systems as working secondary standards.


26

The RS-703A Automated Calibration System collects a data point on a RD Radian standard every 5 (five) seconds on up to sixteen standards simultaneously, collecting literally thousands of data points on an overnight run. In addition each RS-703A provides computer control over an environmental chamber to ensure proper temperature range operation of the standard being tested. Please contact Radian Research for further information on recalibration and recertification services.

5.4 FuseReplacementFuse replacement is not very likely because of the elimination of the primary side switching. However, fuses are included and are accessible without disassembly. There are four fuses: three potential input and one auxiliary power. All fuses are located under the red potential and auxiliary power inputs. Fuse replacement is performed as follows:

1. Remove the red terminal of the circuit with bad fuse by rotating 90o

counter-clockwise and then lift out the unit.2. Remove the fuse by rotating it clockwise in the retaining screw.3. Replace the fuse by rotating it clockwise in the retaining fuse.4. Replace the terminal in the same orientation it was removed and rotate it 90o

clockwise to lock in place.

13.0 Test Accessories

RR-DSMeterDiskSensorThe RR-DS is a reflective pickup assembly used to sense the disk rotation of an induction type me-ter. The pulses generated by the RM-DS are fed into the PICKUP port of the RD-30. Evaluation of different types of meter designs is fully automated when the Built-in Computer option is utilized. The RR-DS is available in two (2) different mounting options. The RR-DS/f Disk Sensor with Field Mount features a Velcro strap that attaches around the meter cover. This allows the sensor to sense disk rotation from the side of the meter. The RR-DS/sm Disk Sensor with Suction Mount features an L-bracket with three (3) suction cups that attach to the front of the meter cover. This allows the sensor to sense disk rotation from the front of the meter.

RR-1HOpticalPickupforInfraredLEDThe RR-1H is used to sense the infrared pulses from the calibration LED of solid-state meters. The pulses from the RR-1H are fed into the PICKUP port of the RD-30. Evaluation of different types of meter designs is fully automated when the Built-in Computer option is utilized. The wide angular displacement of this sensor allows for fast, non-critical alignment. Also, automatic gain control cir-cuitry of the RR-1H assures operation in all ambient sunlight conditions. The RR-1H/v is available for those solid-state meters with a visible calibration LED, and terminates in a BNC Connector instead of a lemo connector. Therefore, the RR-1H/v attaches to port 1 instead of the pickup terminal.

RM-OAOpticalAdapterThe RM-OA Optical Adapter is used with solid-state meters whose infrared calibration pulse is emit-ted from the optical communications port. The RM-OA magnetically couples to the communication port of solid-state meters. The suction cup of the RD-1H is attached to the clear polycarbonate cover of the RM-OA. The RM-OA incorporates a rare earth permanent magnet for exceptional holding power over the life of the product.

RR-KYZPulseInputAdapterThe RR-KYZ Pulse Input Adapter is used to sense the KYZ output pulses of induction or solid-state meters. The Pulses received from the meter’s KYZ output are conditioned and fed into the PICKUP port on the RD-30. The testing of KYZ equipped meters is done automatically with the Built-in Computer option of the RD-30.

RD Current Connector Locking Mechanisim

Appendix: RD Current Connector Locking MechanismThe Radian RD-2X and RD-3X (120A) Dytronic Standards utilize 6mm locking style connectors for the current inputs.

Note: These connectors are very specialized and feature beveled edges and a locking ring. Do NOT use straight ¼” current connector studs. Radian offers various jumpers and adaptors to fit most applications.

When connecting to the current inputs, insert the 6mm current plugs slowly into the current input receptacles on the RD standard. Do not use excessive pressure when inserting. Only a minimal amount of force is required to engage the locking mechanism.

NOTE: Pushing the current plug too hard may engage and then disengage the locking mechanism in one move. To prevent this, gently push the plug into the receptacle and allow the lock to engage.

Once the locking mechanism is engaged, pull on the current plug outward. You should NOT be able to remove the plug.

To disengage the locking plug, firmly insert the current input plug further into the receptacle until you feel a slight click. This click indicates that the locking mechanism is disengaged. You can then pull the current plug completely out of the receptacle.
