| Abstract: | The kinds and characteristics of overvoltage are analyzed according to its waveform measured in the field.As viewed from insulation coordination and reliability,the influences of overvoltage on safety operation of generator which is just put into operation are analyzed.Based on the insulation aging theories in recent years,the method combining statistic overvoltage parameters with operational records is proposed to estimate the residual life of insulation. |
| Keywords: | overvoltage reliability insulation aging |
