A Brief Discussion on Diagnosis for Overheated Fault in Transformers
WANG Pei-zhang;YE Lian-yuan;HE Zhi-wu
On the basis of oil splitting power formula,the following principle is expounded and proved in this paper. 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;. and there isnt a linearrelationship betWeen total hydrocarbon and oil splitting power. This principle can be used as a supplements method tolocate overheat spot in a transformer.
