The front-chopped-wave generator IPG 506 is used for measuring dc spark-over voltage and impulse spark-over voltage of over-voltage protectors according to CCITT / ITU-T, K12.

Dc spark-over voltage:

A linearly rising voltage, rate of rise 100 V/s up to 640 V, is connected to the device under test. The spark-over voltage measured is shown in the display.

Impulse spark-over voltage:

A linearly rising impulse voltage, rate of rise 100 V/µs up to 5000 V/µs, open loop amplitude 5000 V, is connected to the device under test. The spark-over voltage is measured by use of a peak detector. The result is shown in the display. A built-in impulse voltage divider allows measurement of the spark-over voltage by use of an externally connected scope.

Moreover, the insulation resistance of the test device can be measured in the range of 0.5 – 3 GW. Test voltage selectable: 50 / 100 V.

The high-voltage output terminals are located on the top of the generator. They are protected by a dielectric cover with safety interlock.

A switch-unit can be integrated, which allows successive testing of up to 8 devices.

The generator excels by its compact design, simple handling and precise reproducibility of test impulses. It 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. A standard USB port provides the ability to print a summary of the test parameters to a USB stick.

The software program IPG-REMOTE allows full remote control of the test generator via Ethernet light guide 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) Moreover all generator functions may be computer controlled via the isolated optical interface.
