The BT 500-IS-1 Cable Fault Converter is mainly used for converting high-resistive cable faults in signal, control and telecommunication cables into low-resistive ones.

Its source of adjustable voltage 0 to 2 kV has a balanced output, i. e. a faulty pair of wires can be connected to its output terminal balanced to earth.

In conjunction with a special Sheath Pre-locating Device of type MVG 5, sheath faults can be pre-located. Using this accessory device, the following measurements can be taken:

• Sheath fault pre-location on shielded telecommunication and control cables with PVC or PE-type sheath
• Sheath fault prelocation on shielded medium-high voltage cables with PVC sheath (test voltage up to 2kV)

Pin pointing is carried out by means of the Earth Fault Locating Device ESG 80-2 by the method of measuring the step voltage. Moreover our new Cable Fault Converter BT 500-IS-1 has some more special features such as:

• Continuously adjustable output voltage in voltage ranges 500, 1000, 2000 V
• Floating Potential at either outputs
• Protection against overload by voltage and current control
• Fault location at reduced power to prevent damages to adjacent wires or cables
• Indication of voltage and current by two analog indicating instruments
• Automatic discharge unit provides for removal of residual charge and for earthing the test object
• Clock-controlled operation of the voltage source to prevent the drying-out of faults when pin pointing sheath faults

Accessory equipment:

• Earth Fault Locating Device ESG 80-2
• Earth spikes with measuring leads EEB
• Sheath Fault Pre-locating Device MVG 5
• Emergency-off switch NAG 1 for stand-alone operation
• Emergency-off switch NAG 2 for operation with MVG 5
