Electrical power testing

Surge or Impulse Winding

The “Impulse Winding Test” is a “non-destructive” technique that applies a high speed and low voltage pulse to the DUT and adds an impulse voltage on the oscillation capacitor (Cs) of the parallel coil so that the parallel capacitor and coil will generate an LCR oscillation.

Surge or Impulse Winding Uses:

  • Surge/Impulse winding testing should be performed as a routine during the production and also when wound components (magnetics, motors) are serviced. … However, if the surge test is used to find the material fault at the production stage then life time of the electric motor is increased.
