Megavar engineers use this unit on commissioning projects across Australia. Hire it from a team that knows it inside out.
It is used to test medium-voltage power cables using VLF AC voltage. It performs withstand testing and simultaneously evaluates the condition of cable insulation using Tan Delta diagnostics.
Tan Delta is a diagnostic method used to assess the quality and ageing of cable insulation. A higher TD value typically indicates moisture, contamination, or other degradation in the insulation.
The HVA 28 outputs up to 28 kV RMS (40 kV peak) at 0.1 Hz, suitable for cables rated up to 15 kV and higher, depending on testing standards.
Yes, it complies with IEC 60502-2 and IEEE 400.2 for VLF and TD testing.
Yes, the unit includes internal memory and allows results to be exported via USB for reporting and analysis.
Yes. The unit is compact, lightweight, and housed in a durable field case. It features an easy-to-use interface and runs from standard mains power with no need for batteries.
The HVA 28 is commonly used in cable commissioning, maintenance programs, substation work, wind farm installations, and cable fault troubleshooting.
The rental includes the HVA 28 test unit, HV and ground leads, carry case, and user guide. Setup and technical support are available on request.
