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 (ungrounded).
In conjunction with a special Sheath Prelocating Device of type MVG 5, sheath faults can be pre-located. Using this accessory device, the following measurements can be taken:  | Sheath fault prelocation 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 |
