Development of a GIS fault location system

Abstract

This paper describes a series of development tests carried out when developing a fault location system applied for the main bus of GIS (gas‐insulated switchgear) by using shock pressure relays. In the main bus of this GIS, each gas section per bay is connected by gas pipings. This paper also refers to the basic construction of the software of the fault location system actually applied to GIS with rated voltage less than 168 kV. © 2000 Scripta Technica, Electr Eng Jpn, 131(2): 20–29, 2000
