On the basis of the theoretical analysis of the fault of the electric energy metering transformer

the PCAELM model is applied to the fault diagnosis of electronic transformer in metering system. Using the advantage of obtaining good generalization performance at a very fast speed

ELM can be used in transformer fault diagnosis. We pick up 8 operating parameters of electric energy metering system as input to ELM. The normal state of the transformer and the nine main kinds of fault types are expressed by the label No.1-10. The samples are collected to train ELM

and eight cases are selected to test. The results show that the PCA-ELM model has a good effect on the fault diagnosis of transformer faults.
