utility fault finding in Southern CA and Beyond

Pinpoint the Problem. Restore Power with Precision.

Find the Invisible Faults

Targeted Solutions for Power & Communication Lines


Our Utility Fault Finding process identifies breaks, shorts, and discontinuities on conductive lines — from electrical feeds to data cables.



We combine specialized signal injection, sectional isolation, and advanced correlation techniques to pinpoint problem areas that standard locates can’t detect.
