| Abstract: | The effect of various parameters on amplitude and frequency characteristics of current coupler is comprehensively analysed, and a Rokovsky coil type current coupler with optimal amplitude freguency characteristics has been developed. Electromagnetic coupling detecting method has higher sensitivity in compare with capacitance coupling detection method recommended by IEC 270. The detection of defected XLPE cable section, showed that electromagnetic coupling method can better reflect the characteristics of partial discharge of the cable. |
| Keywords: | XLPE power cable partial discharge detection electromagnetic coupling |
