Description Hipotronics CF Series
testing 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. All models feature a
continuously adjustable impulse rate from three to thirty
seconds.
70 kV dc proof
tester.
100 mA burner.
0-25 kV dc thumper.
Operates from 120 V
ac line or portable generator (220 V ac is available as an
option).
Model CF70-12 is a 25
kV, 12mF thumper and the CF70-24 is a 25kV, 24 mF thumper.
Both units combine a 70 kV dc proof tester, a 100 mA burner
and a capacitive discharge fault locator (thumper). Absolute
accuracy of the impulse repetition rate is achieved by using a
unique, motorized spark gap. Each unit also has an internal
radar pickup for the Model M602TDR.
