  • Page 4: About The Operator Manual

    This Operator Manual is organized to provide information on the CDS Series in steps that familiarize the new operator with the entire scope of operation of this test set.

  • Page 5: General Information

    HVI CDS series fault locators all have built in Arc reflection filters for use with most TDR’s (RADAR) on the market at thump voltages up to 25 kV.

  • Page 6: Features And Specifications

    M A N U A L Features and Specifications 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 lowest voltage to quicken fault location while not overstressing the cables and terminations.

  • Page 10 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.
  • Page 11 The use of this switch provides a constant energy for capacitor discharge even at lower output voltages. When in any one of the OFF positions, the high voltage cannot be energized. If the switch is operated during testing, the output will de-energize. When changing tap positions allow 20 seconds for the motorized switch to achieve final position.

  • Page 12: Setting Up The Equipment

    SETTING UP THE EQUIPMENT The setup of this equipment has been minimized by careful consideration for the operator during design. The CDS Series’ one-piece FIELD PORTABLE construction makes this the preferred unit for fault locating. Select a location for the unit that will allow easy viewing of the meters at a safe distance from the test cable.

  • Page 23: Performing Special Operations

    The CDS SERIES of fault locators use precision metal film resistors for measurement and calibration of the voltmeter and the current meter. The use of these resistors in both the high voltage tank and the metering circuits has minimized circuit drift due to aging and temperature.
