Power secondary equipment constitutes a system, not just the device itself, such as AC, DC, control loop, etc., as part of the circuit has no means of monitoring, the real-time technical analysis and judgment to the status of the equipment couldn’t be conducted now. Therefore, as for the status quo of the application of electrical secondary equipment, strictly speaking, most of the protections don’t have the condition of condition-based maintenance.
In the power system, the planned maintenance system of electrical equipment exists serious defects, such as frequent temporary maintenance, lack of maintenance or overhaul, and blind maintenance etc., which makes the equipment maintenance cost huge every year around the world. How to reasonably arrange the maintenance of power equipment, save maintenance costs, reduce maintenance costs, while ensuring high reliability of the system, which is a important topic to the system operators. With the application of the comprehensive intelligent systems in condition monitoring and fault diagnosis, such as sensor technology, microelectronics, computer hardware and software, digital signal processing technology, artificial neural network, expert system, fuzzy set theory etc., Based on equipment condition monitoring and advanced diagnosis technology, it makes the state maintenance research developed, becoming an important research field in the power system.
