| Abstract: | Based on the deeply research and analysis of massive on-line monitored data, some factors influencing on the measured parameters of HV apparatus are analyzed. Relationship between dielectric loss factor and phase shift of TV, electromagnetic disturbance, operation and rain is given. The influence of humidity on capacity and the influence of leakage current of arrester on resistive current is discussed. Some proposals for improving the accuracy of measurement are put forward. |
