CF70-12 or -24 Primary Cable Fault Locator - Overview
 

Overview
Haefely Hipotronics CF70-12/-24 primary cable fault locator consist of a DC proof tester, a Burner and a Capacitive Discharge Fault Locator (thumper). These self-contained portable units are rugged, reliable and compact making them ideal for field use, The CF70-12 or CF70-24 has a continuously adjustable impulse rate from three (3) to thirty (30) seconds. Test ratings are a 0 to 70kV DC proof test voltage, a 100mA burn current and a 0 to 25kV DC capacitance discharge (thumper) voltage.

The units can be used with high voltage coupler (HVC-4100 Series) and a time domain reflectometer (TDR1150 or TDR-1170) to quickly provide a specific distance to the fault in feet or meters. This combination of equipment can greatly reduce the amount of high voltage (number of thumps) the cable resulting in reduced damage or degradation to the cable under test.
