D.C. Hi-Pot URD Test Adapters

Inst ruments and Meters – 2450 Features & Applications • Work with CHANCE Phasing Tool H1876 (page 2452) for metered readout • 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 • Field-effective method proves especially beneficial for: o Testing new cable before initial energizing o Testing repaired cable before re-energizing o Testing suspect cable spans for faults • Brass male fitting inside larger end threads onto the meter probe of phasing tool • For testing and subsequent discharging, brass female fitting at smaller end accepts 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" dia.
