SURGE CURRENT GENERATOR 

PG 6 - 2402

Surge current 8/20 µs

2 * ( 1 - 25 ) kA

acc. to IEC 60, VDE 0432

Surge current testing of surge protection devices

The high-current pulse generator PG 6-2402 is designed for surge current testing of electrical components, over-voltage protectors and electronic circuits acc. to IEC, VDE, etc.  It generates standard impulse currents with waveform 8/20µs. Pulse current output amplitude can be set to 2 - 50 kA.

The generator has two pulse current outputs; it allows simultaneous testing of two-gap overvoltage protectors. Paralleling both outputs, the user can get up to 50 kA short circuit current amplitude. Using only one output with up to 25 kA peak output current is possible.

Pulse current output amplitude is controlled by preset of charging voltage. The positive or negative polarity of output current can be selected. The impulse current output is located at the top of the equipment and provides high-current connectors for a plug-in test adapter. A dielectric cover with safety interlock protects the high-voltage output terminals. Upon lifting the cover, switching-off of the generator or mains blackout a built-in high-voltage grounding switch discharges the test object and the internal energy storage capacitor.

The pulse-forming network contains a high pulse-fidelity current viewing resistor for measurement of the output current amplitude and waveform with a scope.

The high-current pulse generator PG 6-2402 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 and 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.

The generator excels by its compact design, simple handling and precise reproducibility of test impulses. Moreover, all generator functions may be computer-controlled via the isolated optical interface.
