HVA34

VLF/DC Hipot Tester

This model replaces the ground breaking and very popular model HVA30. The HVA30 was upgraded to the HVA34 to accommodate the new testing requirements for 25kV rated cables as per the latest revision of IEEE400.2 testing standard.

Arguably the top selling VLF/DC instrument on the market, this instrument has become the standard for testing 25kV rated cables and below. The upgraded model includes an even more powerful output while keeping the same overall weight, physical dimensions, and user interface.

A single piece design, weighting only 44 lbs / 19.5kgs, it is capable of testing up to 120, 000ft / 37km of cable. This is not just a VLF hipot, it also includes a DC hipot, Fault conditioning, Sheath testing, and Vacuum Bottle testing modes all housed in single piece, powerful test instrument.

Features:

  • Test your 25 (Maint), 15, 11, 8, 6.6, 5kV long MV cables
  • Weighs only 44lbs / 19.5kg
  • Perform tests fully automatically
