摘要：
Power apparatus condition monitoring continually or at intervals is important for any power transmission and distribution utility to supply energy with an acceptable level of reliability, quality and safety. Based on the information, critical and cost effective maintenance and repair decisions could be taken to reduce power failures and the resulting damage to infrastructure. The insulation material used in the system degrade due to thermal, oxidative, hydrolytic, electrical and mechanical operating conditions. Also, currently a significant number of power apparatus in any power grid are operating beyond their design life. Operating health condition and remaining life are diagnosed by various off- and on-line monitoring techniques with expert system. In this paper, the current status of R&D work in this field and the readily available commercial instrumentation based on electrical, chemical and mechanical methods would be presented.
