D.C. Hi-Pot URD Test Adapters

For quick, reliable 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. hi-pot-adapter-1763

This field-effective method proves especially beneficial for:

  • Testing new cable before initial energizing.
  • Testing repaired cable before re-energizing.
  • Testing suspect cable spans for faults.

For metered readout, the Hi-Pot Adapters work with Chance Phasing Tool H1876 (page 2452). 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 (page 2455).

Illustrated instruction booklet is included. Units contain high-voltage rectifiers encapsulated in Chance orange 1-1/4″ and 1-1/2″ diameter Epoxiglas┬« housings.

Hi-Pot Adapters measure only 13″ in length for 35 kV unit, and 10″ for 16 kV unit, far right.
