The term surge tester applies to an impulse winding test device. This device is manufactured by SPS electronic under the name ST 3800 G (manual device) and ST 3800 L (generator for the OEM use). This SPS surge tester detects already existing interturn short circuits and makes it possible by means of its special test method to detect prior defects which do not yet represent an electrical interturn short circuit.
The inner insulation of a coil can only be tested with a surge tester, i.e. per an impulse winding test.
Among the practical service of SPS electronic counts for example the maintenance of each test system and testing system directly at the factory. SPS offers loan devices, too. The wide range in accessories offered for the safety test technique is worldwide appreciated by the SPS customers.
