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.
