Condition monitoring system for TransGrid 330 kV power cable

摘要

A condition monitoring system (CMS) has been designed and installed as part of a new 330kV power cable circuit in Sydney, Australia by TransGrid and J-Power Systems Corp (JPS). The principal aim of the CMS is to provide real time monitoring of cable conditions, and to assist in asset management to ensure reliable cable operation. The major features of the CMS are the cable temperature monitoring and prediction functions based on a distributed temperature sensing system (DTS) and fluid pressure monitoring system. This paper describes the CMS as specified and implemented by TransGrid and JPS.
