With the surge tester ST 3800 G (manual device) and the surge tester ST 3800 L (generator for the OEM use) market leader SPS electronic presents a German made high-end impulse winding test device for each purpose.

This surge tester not only detects already existing interturn short circuits but makes it, due to its test method, possible to already detect previous defects not yet representing an electrical interturn short circuit.

The inner insulation of a coil can solely be tested by the impulse winding test.

An impulse winding test device does not merely find application in a laboratory or in development. Its main application is in serial production as a vital test system. To minimize the risk of early failure this safety tester should be an absolute must in production of e.g. transformers, motors, coils or chokes.
