for 3-Pole Gas Discharge Tubes

Rise of output voltage, selectable:

600 V= : 100 V/s

5 kV impulse: 100V/µs - 5000 V/µs Insulation resistance 0.5kW - 3 GW Acc. to CCITT / ITU-T, K12

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, simultaneous plus and minus,  is  connected to the device under test. The spark-over voltage of these two simultaneous impulses are measured and shown in the display.

Impulse spark-over voltage:

A linearly rising impulse voltage, simultaneous plus and minus, 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 results of these two simultaneous impulses are shown on the display.

Two built-in impulse voltage dividers allows measurement of the spark-over voltage, plus and minus, by use of an externally connected scope.

Moreover, the insulation resistance of the test device can be measured in the range of

0.5 kW - 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.

The front-chopped-wave generator IPG 506 feature 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, which are shown on the built-in display, are easily adjusted on the 5" touch screen.

A standard USB interface provides the ability to print a summary of the test parameters and measured values of spark-over voltage whilst testing is being carried out on an USB stick.
