摘要
Abstract
With the constant expansion of distribution network,it is necessary to test the capacitance current and check whether it is over the standard.Comparing several testing-in-field methods of distribution network’s capacitance current,this paper chooses the signal injection method to carry out most of the current tests in field of 27 substations in 10 kV/35 kV systems of Kunming Power Grid,and calculates the currents of the substations at which the measured values are relatively larger,pointing out that the difference between the measured and theoretical values is due to the factors of improper test method,change of system’s operation mode and so on.For several types of abnormal cases,the solutions are given in the paper.关键词
