Model HVA30-7 -Extra Power VLF / DC Hipot Tester
The HVA30-7 Extra Power VLF/DC Hipot model was designed primarily for electrical utilities that have large complex cable networks that demand a very powerful test instrument to overcome the large loads presented by these long cable systems. Capable of testing up to 150,000ft / 45km of cable - it does not get much more powerful than this. This instrument, like all other HVA models, provides a very powerful high voltage DC output in addition to the VLF AC output.
The HVA30-7 model can be used for testing many other electrical apparatus like transformers, motors/generators, switchgear, etc. Its single piece design has one of the highest power-to-weight ratios outputs in the industry.
Like all other instruments in the HVA series, there is no need to connect two heavy pieces of test equipment with interconnecting cables, etc. There is no warm-up period required before use and no insulation oil used in the design that needs to be maintained.
