VLF hipot and VLF testing is as simple as an AC hipot on lower frequency output (at 0.1 Hz). The only way to field test high capacitance loads with AC voltage, like cables and motors/generators, is to use a VLF AC hipot. Lower the frequency, Lower w

How does hand held partial discharge tester function? A handheld partial discharge tester is a portable device used to detect and diagnose hidden electrical faults known as partial discharges (PD) in high-voltage equipment. These testers typically em

Measuring the contact resistance of EHV (Extra High Voltage) circuit breakers is important for several reasons. First, it is a key parameter for evaluating the performance of the circuit breaker. Excessive contact resistance increases the likelihood
