Mechanical characteristics, including the displacement curves of the movable contacts and coil current curves are the most common routine monitoring objects of high voltage circuit breakers to evaluate the machines' condition. Generally, a high-performance mechanical characteristic tester has the ability to offer dozens of parameters consisting of stroke, speed, magnitude of current and so on. Besides,...
The degradation of high voltage circuit breakers is the result of the interaction between the equipment's attributes and the environmental stress such as the electrical, thermal or mechanical stress. Traditional methods of degradation analysis often rely on many theoretical assumptions to offer the detailed relationship between the machine's condition and the failure probability. However, this kind...
