Cable Testing

A substation can only be as reliable as the cable feeding it. We run condition-based cable testing on medium-voltage feeders, terminations, and splices — with results that engineers can actually act on, not just pass-fail.

What we test
  • VLF tan delta and dissipation factorIEEE 400.2
  • Offline partial discharge surveyIEEE 400.3 / IEEE 400.4
  • Polarization index and insulation resistance
  • DC HiPot withstand testingIEEE 400.1
  • Cable identification and phasing
  • Termination and splice inspection
Standards we follow

IEEE 400 (parts 1, 2, 3, 4) · IEEE 510 · NFPA 70B

Apparatus covered

Shielded power cable from 5 kV through 35 kV. EPR, XLPE, and PILC constructions. New and aged cable.

Reports you get

Every visit ends with a documented report: raw test data, calibrated instrument records, anomaly findings with severity ranking, photos, and a clear recommended-action list. Trends are tracked across visits.
