Description Hipotronics CF Series
test systems for fault locating of primary cables 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 CF30-8 has a continuously adjustable impulse rate from
three to thirty seconds. Test ratings are a 30 kV dc proof
test voltage, a 50 mA burn current and a 0-15 kV dc capacitive
discharge (thumper) voltage.
The units can be used
with a high voltage coupler (4100 Series) and a time domain
Reflectometer (TDR) 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.
For additional
pinpointing the HSDAD acoustical detector can be used in
conjunction with the CF30-8 to pinpoint the exact underground
location. While the CF “thumps” the cable the user “listens”
to the thumping using HSDAD and can pinpoint where to start
digging to repair the fault.
