Abstract
The disclosed method prevents hazard such as breakdown, short circuit and fire ignition caused by lightning surge on electrical product. In the method, capacitance in use for absorbing electric potential of shock wave in capacity 9000-12000PF and impulse withstand voltage 475KV-525KV is connected to excitation winding of controlling change of magnetic flux in parallel. Advantages are: high capacity of absorbing electric potential of shock wave, on the safe side and beneficial to raise quality of product.
