HVA45TD

VLF/DC Hipot Tester with Integrated Tan Delta

This unit packs a punch at 45kV peak output and integrated Tan Delta. There is no need to have a separate external Tan Delta instrument with this all-in-one design. Fully compliance with the IEEE400, 400.2, IEC 60502, CENELEC HD620/621 guides and standards. At only 86 lbs / 39 kg this unit is very portable, housed in a rugged IP67 case.

With a high test capacity of 10uF, there are very few loads or cables this instrument cannot test. With the a large 4.3" color display, automatic TD evaluation, and manual and automatic test functionality, DC and AC operation, testing in the field just got a whole lot easier.

Designed for performing diagnostic testing for up to 35kV rated cables and full acceptance testing of cables 25kV and lower, this unit covers most of the MV cables installed today. All instruments are shipped with a NIST calibration certificate, TD Control Center software, corona protection shields, Bluetooth dongle, and accessories tote.
