MAIN POWER
The MAIN POWER circuit breaker provides the power to the control and power circuits. The MAIN POWER
pilot light will light when the power is on and voltage is available through the input line cord. The power
supplied to the input line cord must be from a grounded source rated to match the input power specifications
notedin Table-1.
HEATER
The HEATER circuit provides assistance in keeping the internal components from accumulating moisture in
dampenvironments. The pilotlight will illuminatewhen the circuitis powered.
START/STOP
The START/STOP pushbuttons activate (de-activate) the high voltage power circuits. The LED indicators
provide long life positive indication of the circuit status. The RED (START) LED lights when high voltage is
energized, the GREEN (STOP) LEDlightswhen the highvoltage isde-energized.
OUTPUT ADJUST
The OUTPUT ADJUST control variable transformer sets the output voltage. The 0-100% markings on the
knob indicate the low to high setting. The control must be at ZERO (0) to energize the high voltage circuits.
The output control must always be returned to zero at the completion of testing, prior to de-
energizing the output.
VOLTMETER
The KILOVOLT METER indicates the output voltage. 1-% precision resistors minimize the need for re-
calibrationdue to agingshift.
CURRENT METER
The CURRENT METER provides output current readings for the HIPOT/BURN function and capacitor
charge current in CAPACITOR DISCHARGE mode.
CAPACITOR DISCHARGE MODE
The CAPACITOR DISCHARGE MODE switch presets the control circuits for a single pulse (for use with
TDR)or allows thecircuit torun continuouslyin pulsemode.
OPERATING MODE
The OPERATING MODE switch controls the connection of the capacitor discharge bank and capacitor
discharge solenoids. The HIPOT position is used for high voltage testing without the energy discharge
capacitors in the circuit. The HIPOT mode also connects a current limiting reactor for burning down cables
and limit follow through current in a fault. The CAPACITOR DISCHARGE mode for fault locating cable
connectsthe capacitorbank intothe high voltage circuit and enablesthe dischargesolenoids.
