GeneralInformation
Thissection familiarizes theoperator withthe features andspecificationsof the
CDS Series of Capacitor Discharge/Hipot Cable Fault Locators manufactured by HIGH
VOLTAGE, INC.
Operation of this unit with standard TDR fault locating devices is possible using the internal Arc
Reflection Filter.
TheoryofOperation
With the use of buried underground cables in primary feed electrical installations, it is necessary to
locate faults and repair the cable the cable as quickly as possible to restore power to affected
areas. The CDS Series of Capacitor Discharge/Hipot Cable Fault Locators uses an energy
storage capacitor to provide a pulse of energy to create an audible sound at the fault location for
tracing. HVI CDS series fault locators all have built in Arc reflection filters for use with most TDR’s
(RADAR)on the marketat thumpvoltages upto 25 kV.

FeaturesandSpecifications
The CDS Series of cable fault locating test sets provide continuously adjustable output voltages for the test
and location of faults in primary cables. The constant energy design provides the maximum energy at the
lowestvoltage to quickenfault locationwhile notoverstressing the cablesand terminations.

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.
