High-voltage testing system HVT and HVTS perform DC high-voltage testing of power cables (IEC 60502-2), power cables accessories (IEC 61442) as well as AC high-voltage testing of switchgear, reclosers, dielectric insulators, highvoltage dischargers (arresters), busbars and other dielectric materials with relatively low electric capacitance.
Both devices consist of a control unit and a high-voltage unit. High-voltage units of both HVT and HTVS can be supplied with either transformer oil as an insulating material (HVU-L) or with sulfur hexafluoride as an insulating material (HVU-G). Thus, there are four modifications offered: HVTS + HVU-G, HVTS + HVU-L, HVT + HVU-L and HVT + HVU-G. We recommend using either HVTS + HVU-G or HVT + HVU-L.
The High-power high-voltage testers of HVTSHP series are designed for testing an insulation of high-voltage cables and other non-liquid dielectric
materials with both AC and DC voltage up to 140 kV. Typically this series includes testers which have a test voltage 70 kV DC/50 kV AC 50 Hz and 100
kV DC/100 kV AC 50Hz. There are two common modifications for each model mentioned above which can bring output power value of 7.5 kVA and
17.5 kVA. Any other special models, which have test voltages up to 250 kV with a power of up to 40 kVA are available on customer’s request.
