EMF Meters & Electromagnetic Field Measurement Instruments

AC and DC hipot testers, VLF cable test systems, vacuum interrupter testers, insulating oil testers, and high voltage test equipment for utility and substation maintenance programs.

Insulation integrity is the foundation of electrical safety in every substation, cable system, and piece of high voltage apparatus. Proving that insulation can withstand operating voltage — and detecting degradation before it causes failure — requires high voltage test equipment that is accurate, reliable, and built for field conditions. ProgUSA supplies Hipotronics high voltage test equipment to utilities, electrical service providers, and industrial facilities across the United States, backed by application support, training, calibration, and repair.
