Abstract Overheating protection is widely used as motor thermal overload protection overload protection and stator winding or lead wire short of back-up protection, appear in a loop electrical system or the two loop negative sequence component may also lead to overheating protection. The paper analyzes the two secondary circuit wiring together due to errors caused by current transformer overheating protection maloperationevent, the current loop variable correlation matters needing attention for reference.
