| Abstract: | With the wide application of cable in voltage distribution network,the level of capacitive current of the system increases. More and more researchers focus on how to measure the capacitive current to the ground of the distribution network system precisely and swiftly. A number of causes that influence existing inaccurate measurement of capacitive current were summed up and the measurement methods were introduced. Some measures were proposed to improve the measurement accuracy of the capacitive current of neutral-point indirect ground system. |
