Power utilities and transmission grids rely heavily on regular diagnostic testing of high-voltage transformers and underground cable networks. Breakdown Voltage (BDV) dielectric testing of transformer oil prevents catastrophic flashovers and insulation degradation.

Pinpoint Cable Fault Locating

Using modern acoustic and thumper surge wave generators, electrical engineers can accurately trace buried cable routes, identify sheath faults, and pinpoint high-resistance faults without destructive digging.
