Abstract

The purpose of the present invention is to provide a transformer grounding system which is able to maintain a stable ground state of a transformer in real time even when disconnection occurs in a ground state of the transformer. The transformer grounding system includes a main grounding device, an inspection device, and a sub-grounding device. The main grounding device is electrically connected to a neutral point of the transformer having a three-phase neutral point, and includes a first reactor having a first reactance to ground the transformer. The inspection device is electrically connected to the main grounding device, and checks whether the main grounding device is disconnected. The sub-grounding device includes a second reactor having a second reactance while being electrically connected to the main grounding device and the inspection device. When the disconnection of the main grounding device is inspected by the inspection device, the sub-grounding device is electrically connected to the transformer in order to ground the transformer.
