There are hardly any other longer-lasting, more robust and cost-effective testing devices than the two-piece high-voltage testing devices of the PGK HB series. They generate step-less adjustable DC test voltages with positive or negative polarity or optionally network frequencies. In the operating parts, there are displays for current and voltage, the safety control unit and a variable voltage transformer. The high voltage part contains an oil-insulated high-voltage transformer, and, according to the mode of operation either a rectifier bar (DC) or a resistance rod (AC). The polarity of the DC test voltage is changed by rotating the rectifier in the high-voltage part.
PGK HB Features
