Corrosion Failure Analysis of Aluminum Alloy Flange of Current Transformer in ……
Substation current transformer (CT) is an important equipment of substation. It mainly undertakes the function of current conversion and electrical isolation, provides current for various instruments and relay protection, and isolates secondary system from high voltage to ensure the safety of person and equipment. Therefore, the normal operation of CT directly affects the safety and stability of substation transmission and transformation. On-the-spot investigation shows that the corrosion of CT pressure release film flange is serious in many substations in coastal areas, which directly affects the normal operation of CT and poses a serious threat to the safe and stable operation […]
