Pure Sinusoidal VLF/DC Hipot with 200kV

Transmission Class Cable Testing Equipment

The HVA200 finally provides cable owners a cost-effective, practical solution for testing their transmission class cables in the field. Ideally suited for testing 138kV transmission cables to 1.7Uo.

The HVA200 provides AC test voltages up to 140kV RMS / 200kV Peak and DC up to +/- 200kV.

The unit is equally at home in the field and laboratory environments. It can be installed on a Trailer with retractable tarp that allows fast, easy and flexible test setup and tear down in a variety of field environments.

The HVA200 excellent withstand testing capability can be enhanced with the optional Tan Delta and Partial Discharge diagnostics interface providing the cable owner with a complete cable testing solution.
