For testing high voltage electrical equipment, AC dielectric test equipment can provide accurate indications of leakage current, in addition to valuable insight regarding the insulating characteristics of electrical apparatus. Using equipment such as an AC high potential test set can help in rapid detection of impending insulation failures and provide assurance that equipment is safe to operate.
Test equipment such as the High Voltage ALT-120/60 120kV / 60kV AC Hipot provides the ability to perform high potential testing at the power system frequency and can be utilized for testing aerial bucket trucks, work platforms and liners. In addition, the unit will detect faulty insulation, compromised shielding or issues with terminal spacing in other electrical apparatus. High Voltage test equipment can be used to specifically isolate leakage currents that are an indication of the insulating characteristics of insulating materials. When leakage currents increase, it is normally identifying damaged or degradation of the insulation over time. The ALT-120/60 provides adjustable and continual output up to 120kV and will meet many of the testing requirements for high potential testing at power system frequency.
For portable AC hipot testing solutions, the High Voltage PFT-503CM 50kV 3kVA AC Hipot model offers lightweight durability for use out in the field under tough testing conditions. This test set's high power performance comes in a one-piece unit, and is appropriate for testing substation apparatus, rotating machinery and much more. Input is 120 V at 60 hertz with a maximum output capability of 50 kV.
