Section 4 – Start-up Procedure
Place the system in service by following these steps:
4.1 Energize Circuit
Closethedisconnectswitch(SW1).Formedium-voltageequipment,closethehookstick-operatedline-fuse
disconnect also. This will connect the equipment to the power system.
4.2 Entering Setup Information
Enter the setup information through the operator’s panel per the instructions given below. The system NORMAL
green light should be illuminated on the operator panel, indicating the presence of power and that no fault or
under-condition is present.
4.3 Ground Fault Alarm Test
With Test Resistor
This test actually places a controlled ground fault on the system within the enclosure through a test resistor.
The test resistor is connected between a phase conductor and ground, so the test circuit begins at a phase,
goesthroughthetestresistortoground,fromgroundthroughtheneutralgroundingresistor,andnallytothe
PulserPlus Pro™ module.
The readings on the PulserPlus Pro™ module will be lower than normal readings due to the test resistor
connected in series with the neutral grounding resistor. The purpose of the test resistor is to avoid a phase-
ground-phase fault if an actual ground fault were to occur during testing. The resistor would be connected
between the two phases.
Enter a test value in the Fundamental Voltage Hi Limit Setpoint. This test voltage needs to be calculated
depending on the actual resistor values. Although 100 volts is typically used for a test value, the schematic
drawings provided with the PulserPlus Pro™ unit should be consulted.
The equation below can be used to determine a non-typical test value.
Vtest =(VL-N/(RGF + RT-G)) RGF – 10V
Where: Vtest is the test voltage to be entered in the Fundamental Voltage Hi Limit
VL-N is the line-to-neutral system voltage
RGF is the resistance of the neutral grounding resistor at the chosen tap
RT-G is the test-to-ground resistance – see schematic drawing
Press and hold the SYSTEM TEST pushbutton on the operator’s panel to activate the ground-fault circuitry.
After a delay, the green NORMAL light should turn off, and the red GROUND FAULT light should start to blink. In
addition, the audible alarm will sound.
