PG 10-504: 10kV Surge CWG

PG 10-504

Combination Wave Generator

The Combination Wave Generator PG 10-504 is a combined impulse-current-/impulse-voltage generator which, for high-impedance loads, RL > 100W, delivers a standard impulse voltage with waveform 1.2/50µs and, for short-circuited output, a standard impulse current with waveform 8/20µs.

The generator allows surge testing of components and devices, the galvanic coupling of surges to cable shields, shielded enclosures and cabinets as well as testing electromagnetic compatibility, EMC, of electronic devices and systems against pulsed and conducted interference.

Using an external Coupling-/Decoupling Network allows superimposition of the combination wave generator's output to the mains voltage of the device under test. The test set-up is suitable for surge immunity testing of electronic systems and devices full compliant to IEC 61000-4-5 and IEEE 587. Demonstrating such immunity is generally a requirement for compliance with the requirements of the European EMC directive, a necessary step leading to the final attachment of the CE mark.

Executing surge immunity tests at power supply a line triggering of high-voltage pulses is accomplished synchronous with mains. The precise trigger point can be shifted between 0 to

360 ° after the zero crossing of the mains voltage. The polarity of the output voltage is selectable. Positive, negative or alternating polarity of the output voltage can be preselected.

The PG 10-504 excels by its compact design, simple handling and precise reproducibility of test impulses. The output current- and voltage waveforms, due to built-in sensors, can be recorded via separate signal outputs for current and voltage.

The generator features a microprocessor controlled user interface and a 7” touch screen unit for ease of use. The microprocessor allows the user to execute either 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 touch screen.

A standard USB port provides the ability to print a summary of the test parameters to a USB stick.

Moreover, all generator functions may be computer controlled.

The software program PG-REMOTE allows full remote control of the test generator via fiber optic Ethernet interface as well as documentation and evaluation of test results, accordingly to the IEC 17025. To record definite impulses, it is equipped with an Impulse Recording Function (IRF)
