초록
VCB, with its big arc extinction in very short switching time, produces the high switching surge voltage which may cause the breakdown of motor insulation or acceleration of insulation deterionation. To protect motor winding insulation, we developed the computer algorithm for simulating the surge occurred in VCB by EMTP. And we established the effect of the C-R surge absorber by the surge measurement in the motor-VCB circuit.
