| Abstract |
The HIF(High Impedence Fault) that occurs in the distribution system is not just a simple system failure, but it can cause very dangerous situations such as fire (forest fire) or electric shock to the public. In order to detect this, an adaptive tuning method for phase current difference (SDI [Sum of Difference Current]) has been disclosed, but it has not yet been verified in the domestic distribution system. In this paper, a detection algorithm is implemented and supplemented, and the result of confirming the validity of the SDI detection method using the fault current waveform of the HIF obtained from the domestic distribution system is presented. It is expected that this study will prevent non-detection and false detection of HIF. |
