Cable & Insulation Testing

VLF Hipot Testers

Very low frequency AC hipot test sets for after-laying, acceptance and maintenance testing of shielded power cables, generator stators and motor windings.

Eight models from 30 kV to 90 kV peak output, in split two-piece and self-contained single-unit formats. The TD variants add tan-delta (dielectric loss) diagnostics and DC and sheath testing, so one instrument covers both the withstand test and the condition assessment that follows it.
