Neutral Current Reduction Module: Triplen Trap
ADVANCED SYSTEM PROTECTION FROM NEUTRAL CURRENTS
Harmonic Heating: A Smoking Gun Harmonics in today’s office power systems burn contacts, melt insulation, corrupt digital signals with electrical noise and cause intermittent surges and interruptions that plague data center managers and facility engineers alike. The electrical systems of yesterday’s office buildings were not designed to support today’s ever growing electronic office. Most of the plug loads contain switch mode power supplies (SMPS) drawing non-sinusoidal current, which overload building wiring and cause premature transformer failure. PDI’s Triplen Trap reduces the negative effects of non-sinusoidal current.
Reduce Neutral Currents to Withstand Non-Linear Loads Phase currents in a three phase system combine on the
neutral conductor where the current can be as high as 1.73 times the phase current. If the phase currents are close to full load, the neutral conductor will be overloaded. This is especially true in older buildings where the neutral conductor was rated for the same ampacity as the phase conductors. Triplens are the third order harmonics (3rd, 9th, 15th, 21st…) generated by SMPS. Triplens flow between the neutral conductor and the distribution transformer in search of a low
impedance return path. PDI’s Neutral Current Reduction Module provides the triplen currents with a new return path through the Triplen Trap. Connected to the three phases and the neutral conductors in the building wiring, the Triplen Trap becomes the low impedance return path for the triplen currents in the neutral conductor. Designed for retrofits or upgrades to existing buildings, the Triplen Trap does not require removal of transformers or disconnection of power to the loads. Connected in parallel with the building’s electrical system, the Triplen Trap reduces neutral harmonic currents by at least 67% (see table, reverse side).

PDI WaveStar™ StaticTransfer Switch
LOW INRUSH TRANSFER UTILIZING THE
PDI VOLT SECOND SYNCHRONIZATION (VSS) METHOD
Introduction
One of the limiting factors in applying static transfer switch-es (STS) in mission critical facilities has been the inabilityof the electrical infrastructures to withstand the transformerinrush when switching occurs on the primary (or 480 volt)side of the transformer. Inrush currents can reach as high as10-12 times the transformer rating, causing breakers andmolded case switches in the STS (or devices upstream) totrip, creating an outage in the facility.
PDI’s patented Volt Second Synchronization (VSS) transferalgorithm controls magnetic inrush current in transformerloads and limits it to 1.5 times the rated current. The transferoutage time and the waveform distortions during transfershave an effect on non-linear loads that are connected to thesecondary side of the transformer. Short transfer outagetimes and waveform peak conservation algorithms are nec-essary for any STSs that feed non-linear loads.
Typically, non-linear loads, servers, and other computersuse Switch Mode Power Supplies (SMPS) which generatenon-linear load currents. The SMPS receives AC power fromthe transformer and generates DC power for the internallogic. SMPS only draw power from the peaks of the inputpower waveforms; RMS values are associated with linearloads and evaluations based on linear RMS loads will notprovide accurate data for evaluation of SMPS applications.
To conserve all voltage waveform peaks, the transformeroutage time of each phase must be short enough to assurethat no peaks are lost. Since SMPS generally use singlephase power, each individual phase must maintain power atthe waveform peaks.
There are four methods of achieving low transformer saturation(inrush) currents when the transformer is connected to theload bus of an STS. These methods are as follows:
• Phase Delay Method (referred to as phase displacement method)
• Volt Second Balance Method• Volt Second Wave Shaping Method
(with RMS conservation)• PDI Volt Second Synchronization (VSS) Method
(with Peak conservation)
Phase Delay Method
This method measures the half cycle phase delay from thetime of the disconnect from one source to the reconnectionof the other source with approximately the same half cycledelay; this will maintain volt second continuity.
When transferring from one source to the other when theconnecting source lags the disconnect source, there is adirect relationship between the size of the phase shift andthe length of the outage.
• If the source phase shifts are small, the transfer outageis of short duration.
• If the source phase shifts are large, the transfer outageis of long duration.
The transfer outage time of at least one phase can exceed 15Ms, depending on the source phase shift and detect time.When the connecting source leads the disconnectingsource, the transfer outage is large at small phase angles.
This method is simple to implement but does not supportSMPS very well.
Volt Second Balancing Method
This method determines the volt seconds applied to themagnetic load by the disconnecting source, and determinesthe volt seconds that will be supplied by the connectingsource. The volt seconds applied to the magnetic load cannot exceed the maximum rated volt seconds.
This basic algorithm must be optimized to obtain thedesired waveform during the transfer outage.
The Volt Second Wave Shaping Method (with RMS conser-vation) and PDI Volt Second Synchronization (VSS) Method(with Peak conservation), described below, are two separateand distinct solutions to optimize the limitations of the VoltSecond Balancing Method.
