Digi-Bridge™

Sheath Testing & Fault Location Device

> > Digi-Bridge

The Digi-Bridge™ is a fully automatic, highly accurate high voltage cable insulation & jacket/sheath testing AND fault location test instrument. Housed in a rugged IP65 pelican type injection molded case, the one-piece fully integrated Digi-Bridge can be used for both cable insulation and cable sheath integrity testing.

Its main function, however, is the precise fault pre-location using the tried and tested bridge fault location technique to locate failures in cable insulation and/or the cable jacket-sheaths.

The Digi-Bridge is particularly useful when traditional thumper impulse reflection (TDR) techniques do not work - for example short circuits and resistive type cable faults. In addition, the instrument can be used for cable/jacket fault pinpointing using the step voltage gradient method for direct buried cables.

The Digi-Bridge is an extremely portable test instrument with a long lasting, integrated, rechargeable battery allowing both AC (shore power) or DC (battery) operation.
