For quick, relieable fault detection on underground cables, two units are available for phase-to-phase system voltages up to 16 kV or 35 kV. By converting AC source voltage to a rectified half-wave, these adapters permit testing of cables with a potential level equal to peak source voltage. This field-effective method proves especially beneficial for testing new cable before initial energizing, testing repaired cable before re-energizing and testing suspect cable spans for faults. For metered readout, the Hi-Pot Adapters work with Chance Phasing Tool H1876. A brass male fitting inside the larger end threads onto the meter probe of the phasing tool. For testing and subsequent discharging, a brass female fitting at the smaller end accepts either Chance Elbow Adapters or Bushing Adapters for 15 through 35 kV. Units contain high-voltage rectifiers encapsulated in Chance orange 1-1/4 in. and 1-1/2 in. diameter Epoxiglas® housings.
