Product Details

Multi-stage impulse current generators are designed according to principle of Marx Generator to generate high energy exponential impulse currents.

Mainly for the residual voltage test of complete set of lightning arresters, like 36kV LA test at 20kA, and residual voltage up to 120kV. Also popular for grounding resistance experiment, like 30kA impulse current test for up to tens ohm earth.

Impulse current test systems are mainly used for testing transmission and distribution systems against the effects of direct or indirect lightning strokes or against electromagnetic interference effects.

Primary application of impulse current test systems is the testing of surge arresters, nowadays mainly of the metal-oxide type (MOA) and surge protection devices (SPD). Now they are also widely used to test vehicles, aircrafts, and military applications.
Depending on the broad range of the different designs and tasks of the various equipment to be tested, impulse current test systems have to be adapted for the special testing purposes.

FSHV impulse current test systems can generate 1/20μs, 4/10μs, 8/20μs, 10/350μs, 18/40μs, 30/80μs, 2000μs and other standard impulse current waveforms as per IEC standard, peak current value up to 240kA 8/20μs and 200kA 10/350μs.

Standard test system consists of an impulse current generator (mainly consists of capacitors, resistors, inductors and a spark gap), charging and control unit as well as voltage and current measurement.
