RL-Series pole mounted load break switch / sectionaliser
2
The Nu-Lec Industries RL27 pole mountedgas insulated load break switch is availablein manual and automatic models. Theautomatic model can be configured as aremotely controlled switch, or as asectionaliser. These automatic switchesprovide the features of traditional loadbreak switches and sectionalisers, plus thebenefits of an up to date design optimisedfor automation, remote control andmonitoring, now or in the future.
The development of these new productswas driven by customer demand forimproved return on capital investment inthe distribution network. After carefullyevaluating customers needs, the Nu-LecIndustries RL27 was developed to achieveoptimum performance and reliability,making use of the very latest in availabletechnology in SF6 arc interruption andmicroelectronics. The result is acompetitive world class product of whichwe are justly proud.
Today, your customers, the electricityconsumers, are demanding reducedoutages, and lower tariffs. We at Nu-LecIndustries are continually working toprovide advanced equipment needed fortomorrow’s competitive electricitydistribution system.
In the past, distribution equipment such asload break switches has been purchasedonly to support load growth. Now by usingthis technologically advanced equipment,operating costs will be reduced andrevenue will be increased through bettermanagement of existing plant.
In addition to pole mounted load breakswitches and sectionalisers, Nu-LecIndustries also manufactures a range ofremotely controlled and monitored 12kV,24kV and 36kV automatic circuit reclosers(circuit breakers), and remote control andmonitoring software.This product family isa complete solution for distribution systemautomation.
Reduced Purchase Cost• The RL27 is offered in a modular concept that allows you to purchase a basic
switch and upgrade it in the future to achieve remote control or automationdepending on which model you choose.
• Remote terminal unit (RTU) and modem is included in the standardequipment for the automated switch. No additional RTU, modem, radio powersupply, batteries, wiring, connectors or enclosures are required.
Reduced Installation Costs• For the 15kV product bare terminals are provided and for the 27kV product a
400A insulated cable tail kit.• A cross arm mounting bracket is provided in the standard package.• Commissioning of the unit is simple. Configuration of the automated switch is
menu driven from the Operator Control Panel in the control cubicle (ifordered).
Reduced Operating Costs• In the case of sectionalisers, the integral current sensing logic provides fast
isolation of the fault, reducing damage.• The automatic load break switch or sectionaliser constantly monitors line
current, without the need for additional statistical measurement devices. Thisdata can then be used for forward planning and optimisation of existing plant.This will reduce distribution system losses.
• Long Lifetime, low maintenance equipment reduces lifetime cost.
Remote Control & MonitoringWhen used with a compatible Distribution Automation System (DSA), or SCADAsystem, the Nu-Lec Industries pole mounted load break switches andsectionalisers, support remote control and monitoring to provide the followingadvantages:• Information on load break switch and sectionaliser states and fault current
values transmitted to system control allows fast location of the faulted linesection which reduces travelling time of line crews.
• This same information allows informed remote switching which reduces theaffected area, and quickly restores supply, thus improving quality of supply.
• The load break switch and sectionalisers can be configured and settingsmanaged from system control, without technicians having to visit eachindividual device in the field, to change configuration settings, withconsequent reduction in staffing, and improved system integrity.
Increased Revenue• Supply can be quickly restored to unaffected areas, which results in less
outage time and therefore increased revenue.
Deferred Capital Works• Remotely controlled and monitored load break switches and sectionalisers
give an improved knowledge of the system, and improved system control.Feeder and substation load can then be remotely managed and switched,providing cross re-inforcement of substations, and improving utilisation ofexisting plant. Purchase of new plant can most likely be deferred for aconsiderable period of time.
Introduction and Features
Nu-Lec IndustriesRL-Series
3
Nu-Lec Industries’ range of RL series SF6 gas switches aredesigned to meet the growing requirements for oil free,maintenance free, long life, maximum safety and future feederautomation. The SF6 gas as the insulating and arc quenching media together with puffingprinciple ensure the positive breaking of small current, mainly active load current,cable charging current and magnetising current. The extremely short arcing times(within half a cycle) plus tulip type contacts with arc resistant (Cu-W) materialensure the long switching life and extended short circuit making capability.
The interrupters are ganged together and driven by an over-centering springmechanism. This is operated either manually or by a DC motor in a motorcompartment below the tank.
A manual operating arm allows hookstick operation from ground level. By pulling onthe appropriate side of the arm the load break switch can be tripped or closed. Themechanism is "operator independent" so that it does not matter how fast or slowthe arm is moved by the operator. A motor mechanism is used in feederautomation schemes to facilitate remote control.
Modular designProduct Type MR and RC
Product Type MR comprises an operating mechanism as described above. Anoptional motor pack can be purchased to upgrade from Product type MR to RC.This allows the unit to be interfaced to a Nu-Lec Industries or third party controlcubicle to provide local and/or remote control.
Product Type MA, A and FA
Product type MA comprises an operating mechanism as described above andCurrent Transformers (CTs) and Capacitive Voltage Transformers (CVTs) are builtinto the tank. The CTs and CVTs are available for line sensing in Product Type FA.To provide local and/or remote control, an optional motor pack can be purchased toupgrade from Product type MA to A.
Product type FA includes all options. The CTs and CVTs are connected to thecontrol electronics to provide fault detection, line sensing, measurement andsectionaliser functionality. The control cubicle houses the Operator Control Panel,microelectronics and the electronic controller that monitors the load break switchand provides sectionaliser functions. Combined together, the load break switch andcontrol cubicle form a remotely controlled and monitored pole mounted load breakswitch / sectionaliser.
In Product type FA the control electronics measures the making/breaking currentevery time the load break switch operates. This measured current is then used tocalculate the amount of contact wear each interrupter has suffered and the contactlife remaining is reduced accordingly. The remaining contact life is held in theswitchgear memory and can be displayed on the Operator Control Panel.
Safe designIn the event of an internal arc fault, a vent on the side of the load break switchruptures to vent the over-pressure. This eliminates the risk of explosion ordetachment from the power pole and since the unit is not oil filled, a major firehazard is eliminated.
Product Type MA, A and FA includes two additional safety features. Firstly a LowPressure Interlock which locks the operating mechanism if the gas pressure in thetank drops below a pre-set threshold. Secondly a Mechanical Locking Ring isprovided to lock the operating mechanism when the ring is pulled to the lockposition using a hookstick. The MR and RC products do not include the gaspressure interlock or mechanical locking ring but does include the over-pressurevent.
Easy InstallationHigh voltage connections on the 27kV models are made with insulated cable tailsterminated on epoxy bushings. The cable and bushings are covered by a grippingelastomeric boot that is filled with silicone grease to form an insulated system.
Bare terminals instead of covered assemblies are used on the standard 15kVmodels.
The switch is mounted using the standard cross arm mounting bracket.

The advanced fault detection, data logging and communicationsabilities of the RL-Series load break switch / sectionaliser aremade possible by the technology housed in the control andcommunications cubicle (suppllied with Product Type FA only). Ithas been designed especially for outdoor, pole mounted operationand is normally mounted low on the pole for ease of access bymaintenance personnel.The cubicle is insulated and designed to minimise any temperature rise resultingfrom solar heating. An internal equipment panel is used to mount all the equipment,including the batteries, storage capacitors, mains transformer, low voltage circuitbreakers, Control And Protection Module (CAPM), operator control panel and radioor modem. These components are carefully located so that the heat generatingparts are at the top, while the battery is at the bottom to keep it cool. In this waybattery life in excess of 5 years can be achieved.
All weather access is provided to the Operator Control Panel through a lockabledoor on the front of the control cubicle. Vents are screened against vermin entryand the door is sealed against the outer with a rubber extrusion. All electronic partsare well protected from entry of moisture and condensation ensuring a long lifetime.
Three models of control and communications cubicle are available, Tropical,Moderate and Temperate. The Tropical version is well ventilated and is suitable forclimates where the ambient temperature can reach 50°C and only occasionallygoes below 0°C, with a lower limit of -10°C.
The Moderate version has reduced ventilation and is used where temperaturesrarely go above 40°C and occasionally go below -5°C, with a lower limit of -15°C.
The Temperate model has a heater installed, making it suitable for climates wherethe temperature rarely goes above 40°C but can fall as low as -30°C.
All three cubicles are fitted with the same electronics and incorporate the functionsof an overcurrent through-fault detector, a sensitive earth fault relay and a remoteterminal unit. Additionally, the electronics measure line current, voltage, real andreactive power, fault currents, and stores these for transmission or off-line analysis.
A unique feature of the RL-Series pole mounted load break switch / sectionaliser isthe built in microprocessor controlled power supply. This provides uninterruptedoperation of not only the load break switch and fault detector, but also thecommunications radio or modem. No other power supplies are required forconnection into your SCADA or Distribution Automation System.
Due to careful design the efficiency of all parts is extremely high, allowing a batteryhold up time of five days after auxiliary supply failure (from fully charged battery,excluding telemetry radio or modem usage). The architecture used has theadvantage that the switch operation is independent of the high voltage supply,relying on a set of batteries charged by the auxiliary supply.
Due to sophisticated power supply management techniques, a switch operation isalways guaranteed when attempted and alarms are raised over the telemetry whenauxiliary power is lost.
A communications radio or special modem can be mounted within the control andcommunications cubicle. A V23 FSK modem is included as standard equipment.

Communications CubicleOverview (Type FA only)
Pole Top Control & Communications Cubicle
Control and Protection Module (CAPM) Circuit Board
Nu-Lec IndustriesRL-Series
The fully automated (Product Type FA) pole mounted load breakswitches / sectionalisers provide many outstanding advantages tothe user. New and innovative features have been made possibleby the intimate way the pole mounted switch and communicationscubicle work together. The block diagram below shows how thetwo items can be interfaced. The heart of the unit is the Controland Protection Module (CAPM) and the intelligent OperatorControl Panel.HV Line signals are connected into the electronics module by direct connection tothe analogue front end. Special extended range current transformers provide arange from 10A to 16,000A for measurement and fault detection. Embeddedvoltage screens accurately image the primary voltage value and phase relationship,allowing measurement of voltage, current and phase angle in the electronicmodule.
Each load break switch / sectionaliser is provided with an operator control panelwhich has a four line liquid crystal display with back lighting for night operation.From here a user can access and program the many measurement and faultdetection features available.
Three levels of user interface with the operator control panel are provided asfollows:
1. Operator Level
This allows basic operation like Trip, Close and display of settings, such as:• Sectionaliser settings and fault history• Line measurements and historical data• Alarms/Status such as:
Auxiliary supply fail, Battery failGas lossLive LineRemote/Local Control
2. Technician Level
This level is password protected at the user’s discretion in the “Engineer Level” andallows the setting of all sectionaliser related parameters.
3. Engineer Level
This is accessible through a laptop or desktop computer and allows setting of thepassword and access to all the Operator and Technician Level functions.
Telemetry InterfaceThe RL-Series pole mounted load break switch / sectionaliser can be interfaced toyour SCADA system either through its built-in V23 modem and a radio, or itsRS232 port and a modem of your choice. A variable voltage uninterruptable powersupply is included for the radio or modem, which can be mounted inside thecommunications cubicle. Almost all telemetry protocols can be supported. DNP3and IEC870 are two of the available protocols.
Computer InterfaceThe Windows Switchgear Operating System (WSOS) is an advanced personalcomputer based software package to allow off-line and on-line programming,monitoring and control of a load break switch /sectionaliser via the RS232 port.This is available as an option to the basic RL-Series load break switch /sectionaliser.
Remote ControlAs an additional option, Nu-Lec Industries offers the WSOS multiple connect PCbased software package to individually remote control and monitor a population offield mounted reclosers and/or load break switches. The system communicates withthe control cubicle by either cable, fibre optic, telephone line or radio. WSOSprovides additional features such as alarm and event handling, dial in and dial outfacilities and report generation.
