Features and Benefits

The PTS-300 and PTS-300F are CE marked DC Hipots designed as a two-piece system with a small, portable controller and a single piece high voltage section housed in a fiberglass cylinder with a spinning output.

Like all HVI products, the PTS-300(F) is designed to be rugged and reliable, equipped with all the features needed for portable maintenance testing of new or service aged electrical apparatus and cables.


  • Two range voltmeter and five range current meter
  • MΩ readings at any output voltage (w/analog meters)
  • Insulated return guard circuit to bypass stray leakage currents
  • Rugged case (field) with cushion grip handles and storage for leads
  • Internal discharge resistors to assist external bleed resistors
  • External safety interlock provision
  • Automatic transit protected meters rated 100 uA for durability
  • Benchtop or field controller available, analog or digital metering
