DSG type directional ground relay will be used for ground fault protection of high voltage distribution and receiving line in non-grounding system. In case of discharging much current between cable and earth in protechtion area, this relay will be applied. This relay will select the fault line among many the fault line. And then the fault will be minimum |

* Ground transformer (GPT 3ry 190V or 110V) and zero phase current transformer(ZCT:200/1.5mA) should be used for coordination * This relay may be misoperated by vibration and impact of switchgear because it is very percious * In condition of being used in place of happening vibration and impact, it should be used with OVGR of DVG type |
