What are the normal patrol items for voltage transformers? -ERG

Answer: The items that the voltage transformers normally inspect are: 

(1) Whether the porcelain parts have crack damage or abnormal sound discharge. 

(2) Whether the oil mark and oil level are normal and whether there is oil leakage. 

(3) Is the terminal block loose? 

(4) Whether the joint is discolored or not. 

(5) Whether the moisture absorption agent is discolored. 

(6) There is no abnormality in the voltage indication.
