HIGH VOLTAGE VLF HIPOT

dielectric strength and insulation resistance testing instruments, namely, very low frequency AC testers for AC field testing dielectric of cables and electrical apparatus; portable dual-range kilovoltmeters for testing overhead electrical apparatus, such as transformers, vacuum bottles and interrupters, switchgear, etc. and also for applied voltage testing of rubber goods/safety equipment, motors, etc.; megonmeters for DC proof testing dielectric strength and for testing insulation leakage resistance; and aerial lift and bucket truck testers
