Algorithm of fault filter in tight coupling distributed system;

In 2006,incipient fault caused by overheating fault inside No.

The article analysed the cause on overheating fault from five aspects,and expounded repaired ways.

Wind-sand weather and special structure of knuckle assembly are found the main reasons for inducing overheating fault of this type of isolator.

A fault trend prediction problem for a class of exponential fault process is studied.

Finally,according to parameter estimation and linear correlation test,the fault process of turret systems was shown to fit with the updated process model.

Whenoverheated fault occurs on a electric circuit,total hydrocarbon producing rate varies directly in proportion with V ;whilethe overheated fault occurs on the magnetic circuit, the producing rate varies in proportion with I2;.

To increase accurate rate of determining overheat faults of transformer,to find out and eliminate faults and to assure normal operation of the transformer,the faults may be found out through periodic preventative tests of the transformer.

After analyzing the mathematical models of all kinds of faults, this paper proposes an isolation method based on structured residuals, which can isolate sensor/actuator faults and process faults.
