Characteristic
The Surge Tester, or pulse coil tester, is an instrument designed for testing coil-type products. It can test products containing all built-in coils, such as transformers, motors, switches, generators, and inductors. It is capable of detecting inter-turn short circuits in the coils, identifying insufficient self-insulation performance caused by various factors during the manufacturing process. For example, it can detect issues such as air bubbles in the insulation varnish, thin insulation at certain points leading to eventual breakdown and leakage of current after some usage time, or scratches on coils during assembly causing inter-turn short circuits.
When inter-turn short circuits occur in the coils, it results in changes in resistance and inductance. Such changes cannot be detected by conventional low-voltage instruments. The Surge Tester applies instantaneous pulses and high voltages to trigger inter-turn short circuits, thereby pinpointing the problematic areas. Unlike the Hipot insulation resistance tester, the Surge Tester operates with low energy release due to its use of instantaneous pulses, making it a non-destructive testing method.
In terms of detection capabilities, it provides area comparison, identifies waveform differences caused by variations in resistance and inductance between test objects and samples. It also performs corona calculation, automatically identifies short circuit points from waveforms, marks corona, and compares inductance values based on waveform frequency in high-voltage testing.
