PG 20-10000 Surge Current Generator 70kA

The surge current generators PG20-10k generates standard impulse currents with waveform 8/20 µs according to IEC, EN, VDE. Pulse current output amplitude is controlled by preset charging voltage and can be adjusted up to 70 kA. The generator is designed for testing electrical components, over-voltage protectors and surge protection devices. The generator possesses an electronically regulated high-voltage power supply, which allows an excellent reproducibility of the pulse output amplitude.

pulse current test of surge protection devices

The generator is designed for testing electrical components, over-voltage protectors and surge protection devices. The generator possesses an electronically regulated high-voltage power supply, which allows an excellent reproducibility of the pulse output amplitude.

The pulse-forming network contains a pulse-fidelity current viewing resistor for monitoring the output waveform. The impulse current output is located at the top of the equipment and provides high-current bolts M12 with a changing test adapter M12.

The generator features a microprocessor-controlled user interface and display unit for ease of use. The microprocessor allows the user to either execute standard test routines, or a ´user-defined´ test sequence. The test parameters, which are shown on the built-in display, are easily adjusted by means of the rotary encoder. A standard parallel interface provides the ability to print a summary of the test parameters whilst testing is being carried out.
