Study of Wireless Secondary Connections in Gas Insulated Switchgear

The paper first discusses the feasibility of the wireless communication in GIS (Gas Insulated Switchgear) substation. The signals inside GIS according to ISA100 standard are first classified and then a scheme to transmit some of the signals by ZigBee wireless is given. A demo example is shown to verify the proposed scheme. In the end, some future modifications and conclusion are discussed.
