PGK 50 E DC high-voltage test device
The portable PGK 50 DC HV tester is used for DC voltage testing up to 50 kV of paper-insulated mass-impregnated cables and electrical equipment in the medium-voltage network.
Manufacturer: BAUR (Austria).
Description
Sensitive current measurement permits the detection of extremely small insulation currents, which are used to determine insulation resistances up to the tera-ohm range. An external curve tracer can be connected to the PGK 50 to record the measured current in relation to time.
The integrated discharge unit operates automatically and independently of the device situation, even in the event of power failure. A clear switching noise can be heard. The discharging resistance is designed for a max. discharge energy of 8 000 J.
Features
- Negative test DC voltages up to 50 kV
- Integrated timer (1-30 min) with automatic switch-off of the high voltage and triggering of the discharge unit
- Continuously adjustable output voltage
- Safety control unit according to EN 50191
- Ammeter with 6 measurement ranges from 1 μA to 100 mA
- All connection elements and cables are in a robust case
- Short-circuit-proof design
- Connection for external emergency off unit, external door contact and signal lamps
- Connection for external curve tracer for recording the test current
