چکیده :

Nowadays, circuit breakers (CBs) condition monitoring is essential due to the importance of the performance of these critical elements in the stability of the power grid against various faults. Exposure of the interruption chamber including main and arc contacts to high voltages a long with the lack of access complicates the online condition monitoring of the CBs. Measuring the resistance of the contacts, the amount of current, and the energy passing through the CB during the operation are usual methods of CB condition monitoring. In this paper, a new method based on frequency analysis is proposed that is able to detect defects related to the non-connection of the fixed and moving parts of the main and arc contacts and shows that these defects can be distinguished from each other with proper accuracy.
