T/CEEIA 321-2018 Mechanical fault testing guidelines for isolation switches - Torque-angle method
Basic Information
Scope
Scope: This standard provides the terms and definitions for testing the mechanical faults of disconnecting switches based on the operating torque-angle analysis method, the requirements for testing instruments, testing methods, and the determination of test faults. This standard applies to the on-site testing of open-type disconnecting switches with a voltage rating of 40.5 kV and above.
