Overview
The WB20CB open and short locator is a highly accurate instrument designed to detect OPENS in individual conductors and SHORTS between neighbouring conductors of various type cable. As an open cable fault locator the WB20CB locates position of break in one wire of a pair using a 0 to 1kV AC power supply.

As a short locator and high voltage bridge, the unit locates the position of a short between a pair of wires using a 0 to 20kV DC power supply. The short can be a copper cross, a high resistance or an infinite resistance high voltage arc.

The TDR 1170 requires a high voltage coupler to interface to a cable fault locator (thumper). The cable fault locator then provides the voltage and current to enable the TDR 1170 to quickly and definitively locate cable faults. Included with the TDR 1170 is a software package to allow the stored data to be viewed on a PC and also be printed and analyzed by personnel or by training teams.

 

 

Features

  • HV Hold - Requires the user to be at the control panel and holding the HV ON push button to provide a high voltage output for either open or short locating.
  • Ground Meters - All meters are at ground potential to help guard against shock.
  • Phase Reversal Switch.
  • Zero Start Interlock - Ensures that the voltage control adjustment is turned to zero volts when the high voltage transformer is energized.
  • Gravity Operated Solenoid - Discharges the test object when the power is turned off. This provides added safety for the operator and the instrument.

 

  Benefits

  • Three tests in one unit - Tests for discontinuities (OPENS) in either conductor in a pair of conductors and locates the position of existing SHORTS between the two conductors. Also capable of performing a DC proof test.
  • Variable HV output - Allows the location of low and high resistance shorts not possible with low voltage TDR's.
  • Rack Mountable - Easy installation into a 19-inch rack.
  • NIST Traceable - significant cost savings on outside calibrations.
