High-Voltage Pulse Generator IPG 809

Surge testing of

• X- and Y- capacitors Cx = 0.1 - 27 nF
• 1.7/46 µs
• 0.2 - 8.0 kV
• IEC 60384-14, EN 132400
• VDE 0565

 The High-Voltage Pulse Generator Type IPG 809 is designed for dielectric testing of X- and Y-capacitors with standard impulse voltages 1.7/46 µs –0/+50% up to 8 kV acc. to IEC 60384-14, EN 132400, VDE 0565 etc.

The output peak voltage can be preset continuously from 0.2 - 8 kV. The pulse-forming network allows the generation of waveforms 1.7/46 µs across capacitive loads from 100 pF to approx. 27 nF within given tolerances. A built-in voltage divider allows the monitoring of the output voltage waveform during testing.

The high-voltage output terminals are located on the top of the generator. A dielectric cover with safety interlock protects them. Upon lifting of the cover, switching-off of the generator or mains blackout the test a built-in high-voltage grounding switch discharges object and the internal energy storage capacitor. Test devices are connected to a plug-in test adapter.

The pulse generator IPG 809 features a microprocessor-controlled user interface and display unit for ease of use. The microprocessor allows the user to operate the generator manually or to generate, save and execute a ´user-defined´ test sequence. The test parameters, charging voltage, polarity number of pulses, pulse repetition time 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. Moreover, all generator functions may be computer-controlled via the isolated optical interface.

The generator excels by its compact design, simple handling and precise reproducibility of test pulses and uses maintenance-free semiconductor switches for surge current generation.
