VLF-34E

The HVI VLF-34E is a lightweight, portable Very Low Frequency (VLF) hipot tester designed for field testing of medium-voltage cables. Providing up to 34 kV peak output, it is ideal for acceptance testing, maintenance diagnostics, and fault investigation according to IEEE 400 and IEC standards. The solid-state design offers stable waveform generation, overload protection, and simple operation for field crews. VLF-34E supports sinusoidal output and automated test sequences for mode switching and pass/fail evaluation. Its rugged enclosure ensures reliability in harsh outdoor environments. This model is widely used by utilities, contractors, and industrial plants for MV cable verification.
