| The two-part test sets PGK HB
generate variable AC test voltages of mains frequency or DC voltages
of positive or negative polarity. The
operating unit in 19" design has a voltage and current display,
safety control elements according to VDE 0104 and variable
transformer for voltage adjustment.
The high voltage unit contains an oil insulated high voltage
transformer and, depending on the desired operation mode, a
rectifier rod or a resistor rod. Reversing the rectifier in the high
voltage unit can change the polarity of the DC test voltage. |
