Mechanical characteristic parameter of a circuit breaker (CB) is an important basis to evaluate its performance. Traditional testing methods involve installing complex sensors and cannot perform testing online. A non‐touch testing method based on computer vision technology is proposed in this paper. During operation, we use a high‐speed camera to capture image sequences, and then search for the target...
During the circuit breaker operating process, the of acoustic signal changing contains its machinery state information. Circuit breaker has complex structure, the fault occurrence and development lead to acoustic signal having a unsteady state of the complex characteristics. The paper puts forward a circuit breaker state diagnosis method based on bispectrum and Hilbert-Huang transform. Basing on the...
