PGK 70 HB High-voltage test set

The PGK 70 HB is used to generate continuously adjustable test 70 kV DC voltages with positive or negative polarity and 55 kV AC voltages at mains frequency.

Manufacturer: BAUR (Austria).

Description

The test set consists of an operating unit and an HV unit. The operating unit contains all operating and display elements and allows the HV unit to be controlled from a safe distance. Depending upon the operating mode, a rectifier or resistance rod is used in the HV unit. The polarity of the test DC voltage can be reversed by rotating the rectifier rod in the HV unit.
Features
  • Test voltages up to AC 55 kVrms or DC ±70 kV
  • Oil-insulated maintenance-free high voltage transformer
