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.
