| Abstract: | Basic principles of the Transient Earth Voltage(TEV) method used to detect Partial Discharge(PD) in the 10 kV switchgear are described and the influence of air humidity on PD in the 10 kV switchgear is studied through the experiments.According to the signal amplitudes of TEV caused by PD at different humidity levels,the insulation levels of the insulators in the 10 kV switchgear are assessed based on experience criteria. |
