CF30-8

High Voltage Cable Fault Locating Power Supply

 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.

Hipotronics Inc. has years
of experience in cable fault
locating the toughest
faults. Our line of cable
fault locating equipment is

designed and
manufactured
based upon our
field expertise.
Whether you use
the fault locator
alone or with other
accessories you’ve
got a powerful tool
to help restore
power to your
customers quicker.
