A Problem to be Noticed for On-site Dielectric Loss Measurement of the CVT Voltage Dividing Capacitor |

| Abstract: | The error caused by loose contact in the dielectric loss factor (tanδ) measurement is analyzed. It is shown that loose contact will make the measured tanδof the voltage dividing capacitor C 2 in the CVT larger than it really is ,The method for eliminating this kind of error is proposed. |
