Abstract
A remote monitoring system provides monitoring of basic parameters of substation equipment. Remote sensor transmitter units are mounted directly on live high voltage parts of substation equipment, and take measurements of basic parameters such as temperature and pressure. The resulting data is broadcast by wireless (radio) communications to a ground based receiver. The data is then transmitted to a central data collection computer for further processing and analysis. A large substation may utilize hundreds of remote sensor transmitter units and several ground based receivers to gain the desired coverage.
