HVA60 VLF/DC Instrument

The HVA60 VLF /DC high voltage test instrument is the instrument of choice when customers require a single instrument that can test the full range of Medium Voltage cables available – that is 35kV rated cables and below. This very popular, single piece instrument is widely used on long 35/33kV cable systems found in electrical utilities, wind and solar farms, etc.

PRODUCT DESCRIPTION

VLF/DC Hipots

From the outset, HV Diagnostics was a pioneer in the development a small, portable, single piece oil free VLF (Very Low Frequency) Hipot test instrument that would be reliable, user friendly and more technically advanced than anything available in the industry. The model HVA30 was developed more than 10 years ago, quickly becoming a game changer in the industry making it the most popular VLF/DC unit on the market.

From those humble beginnings, the HVA Series of combo VLF / DC high voltage test instruments have grown and strengthened, both in voltage and power capabilities, while still maintaining the same unique quality and performance. From the smallest, but still incredibly capable VLF unit on market – the HVA28 – to one of the largest – the HVA200, we now offer a full spectrum of VLF / DC units covering a wide range of power and voltage requirements.

These instruments not only test MV (Medium Voltage) and Transmission class cables, they can also test vacuum bottles, cable jackets / sheaths, motors, generators, transformers etc. A very accurate true RMS measurement system measures and records load capacitance, insulation resistance (Megohmmeter), current, frequency, voltage, breakdown voltage and test duration. The HVA series of VLF instruments form the building blocks for the available Tan Delta and Partial Discharge instruments.

The well-known HVA Control Center Software comes free of charge with all HVA test instruments. Firmware updates are also performed free of charge for the life of the instrument and all new instruments are delivered with a NIST traceable calibration certificate.

 

HV Diagnostics HVA60 VLF/DC Test Unit

The HVA60 VLF /DC high voltage test instrument is the instrument of choice when customers require a single instrument that can test the full range of Medium Voltage cables available – that is 35kV rated cables and below. This very popular, single piece instrument is widely used on long 35/33kV cable systems found in electrical utilities, wind and solar farms, etc. The HVA60’s portable design has a total weight equivalent to just one piece of many two piece VLF 60kV units available on the market. In addition, setting up the HVA60 instrument is simple with no cumbersome interconnects between various modules that make up a typical two-piece design.

Having both VLF AC and DC outputs, the HVA60 is not simply a high voltage instrument for testing MV cables, the unit can also be used for testing Vacuum bottles, cable jackets/sheaths, rotating machines, transformers, switchgear, etc. Test reports are downloaded to the instrument’s internal memory or to a USB flash drive.

As with all HVA units, fully automatic test sequences, digital RMS metering, and integrated storage of test results make the HVA60 a top seller.
