Research and Analysis on the Sensor for Testing the Opening and Closing Speed of Circuit Breakers

Elaborate on a typical case of circuit breaker opening and closing speed testing, and demonstrate that the selection of testing sensors has a significant impact on the results of circuit breaker opening and closing speed testing. Comparing and analyzing the advantages and disadvantages of resistive sensors, grating sensors, acceleration sensors, and angular velocity sensors, combined with the specific situation of the production site, it is concluded that rotating grating sensors and angular velocity sensors are more suitable for testing the opening and closing speed of circuit breakers in the production site.
