Title:
APPARATUS AND METHOD FOR DIAGONAL GROUNDING
Document Type and Number:
WIPO Patent Application WO/2021/096187
Kind Code:
A1
Abstract:
Electrical equipment is grounded in order to suppress ground potential rise in a healthy phase due to a failure of a line in a distribution line, to reduce abnormal voltages or prevent the occurrence of abnormal voltages caused by lightning surges, etc., to operate a protective relay when a ground fault occurs, or the like. Grounding is installed by burying a grounding electrode such as a copper rod in the ground and connecting the electrical equipment to be protected with a grounding line, and at this time, a reference value of grounding resistance varies according to the equipment. When grounding electrical equipment such as lightning arresters and transformers, it is necessary to lower a grounding resistance value, but a problem occurs when installing grounding by digging a pit in an urban area to erect an electric pole in that it is difficult to lower the grounding resistance value since it is difficult to install grounding in parallel because roads are paved. Accordingly, the objective of the present invention is to provide an apparatus and a method capable of lowering the grounding resistance value by digging a pit to erect an electric pole, and burying a grounding rod by means of hitting on a side of the pit diagonally in various directions, and installing grounding in series or parallel.
