Catalog ID: 700-DI

HAEFELY HIPOTRONICS 700-DI dielectric testing equipment is designed to perform high voltage AC tests on electrical apparatus. A variety of mechanical configurations are available to suit different installation conditions.

  • Continuously adjustable output voltage
  • Newly redesigned Auto and Manual Programmable Controller
  • Designed to operate from 10% to 100% of the maximum rated output voltage
  • Easily accessible meter for recalibration access
  • Adjustable overload from 10 to 110% of rated output current
  • Backup breaker overload safety
  • Output connected voltmeter and ammeter
  • Zero start interlock ensures that voltage control is at a minimum before HV can be energized
  • Rated current available from zero to rated voltage.
  • Simple to use with minimal amount of setup time and intuitive control panel allows simple testing
  • Surge-compensated HV transformer windings for withstanding flashovers at full voltage
  • Output connected meters ensures for fast accurate readings
  • Surge and transient protection on all meters, transformers etc.
  • Partial discharge testing with low PD levels available at full output voltage (PD levels need to be specified when ordering system and may require additional components).
