ZGF HV DC GENERATOR

Application

ZGF HV DC GENERATORS are used for DC proof testing of high voltage equipment in power engineering. Routine testing of the insulation and leakage is a necessary requirement for surge arresters. Other areas include: Cable breakdown testing, capacitor charging and general laboratory use.

Main Features

  • Switched-mode technology utilizing pulse width modulation to control the output voltage accurately.
  • The divider is an integral part of the unit with external surge limiting resistor.
  • Zero start up. Audible alarm and LEDs for breakdown and over voltage occurrences.
  • High voltage components are air insulated and housed in light weight insulated tube.
  • Aluminum alloy cabinet.
  • Small dimension. Low weight. Carried conveniently.
