HV Diagnostics Inc. products

The smallest VLF/DC unit on the market now includes an integrated Tan Delta measurement system to perform advanced electrical insulation diagnostics. For example, this can be extremely useful when performing advanced diagnostics on cable systems as it provides valuable information as to the condition of the cable insulation and shield.

Our HVA series HVA34 is arguably the top selling VLF/DC instrument on the market, so we added Tan Delta diagnostics to sweeten the deal! This combination allows the user to employ a VLF Hi-potential test while observing Tan Delta diagnostics.

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.

The TD30 was the first small portable VLF TD system with wireless Bluetooth technology that really made performing Tan Delta testing in the field easy to perform. Compared to other TD systems on the market that required several connections to be made or were large and bulky, the TD30 requires very few connections and does not use any special batteries or fiber optic cabling that is prone to damage in the field environment. The TD30 is designed to work with the HVA30, HVA30-7 and HVA34 VLF test systems making it suitable for testing 25kV and below cable systems. The unit is supplied with host of accessories including corona protection, Blue tooth dongle, jumper cable, ground cable, C Type batteries, C Battery Charger etc.

The TD60-MC system uses wireless Bluetooth technology and has an extremely simple test set up making field testing a breeze. Compared to other large and bulky TD systems on the market that require several connections, the TD60-MC requires very few connections and interfaces easily with the HVA60 using a multi-connector (MC).

The PD30E is an ultra-compact partial discharge (PD) measurement and location system that interfaces to the HVA28TD, HVA34TD, HVA34, and HVA30-7 VLF AC test systems. The portable combination with the HVA28TD allows the user to perform VLF withstand, Tan Delta and Partial Discharge with one easy setup.
