Implementation of State-Oriented Maintenance in Power Grid

In order to overcome the shortages of periodic maintenance,the state oriented proper time maintenance has to be carried out.The measures for its implementation are presented:develop on line monitoring technology,strengthen the regular test and sensuous diagnosis of devices,and forecast the change tendency and regularity of device state with statistics.The control of device's initial state is most important.The practice shows that the times of power outage and operation are reduced,the availability is increased and the maintenance cost is greatly cut down.
