Description
Turn-to-turn surge withstand tester uses pulse waveform comparison method,which generate high voltage pulse to
coil windings of motor or other equipment to conduct equivalent over-voltage simulation test. It can correctly and
rapidly determine the quality of turn-to-turnin sulation by observing,comparing and analyzing the displayed waveform.
It can be used for inter-turn and inter-layer insulation strength testing of single-phase motors, three-phase small and
medium-sized motors, micro motors, special motors, power tool motors, transformers (including switching power supply
transformers), relays, and electrical appliances containing electromagnetic wire windings.
