Biddle 651028

This test set is designed to locate cable faults by the high voltage impulse method on cables rated up to 35 kV ac phase-to-phase. This is a combination type system because it combines the three related functions of a dc proof tester, a dc cable fault burner, and an impulse generator, all having a common power supply.

This test set is composed of two main sections: PROOF/BURN and IMPULSE. Both of these sections are supplied with high-voltage from a self-contained high voltage power supply. In the PROOF/BURN mode the test set provides a continuous dc output which is used for the BURN operation as well as for PROOF testing. When in the IMPULSE mode, a high-voltage capacitor is periodically charged and discharged to produce a high energy pulse. This pulse is used as a traceable signal for cable fault locating.

Standard Model (Catalog #651028)

For a broad range of application capability in a portable instrument, this unit delivers 1250 Joules at 25 kV. Although
this unit is heavier than the 15-kV and dual-voltage models, it is still portable for convenient transport to remote sites. The energy output makes this unit effective on direct buried cable and simple conduit circuits.

Specific capabilities include:

• With a 25-kV impulse voltage output, it finds faults on 15, 25 and 35 kV class direct buried or “in conduit” cable.
• The 30 kV proof mode permits acceptance testing of 5 kV class cable and maintenance testing of 8 kV class cable.
• The 30 kV/50 mA burn mode permits simple breakdown testing and fault resistance reduction to locate faults on 25 kV class cable.
