There are three main sources of electromagnetic disturbance to the industrial system: first, space field disturbance, which enters the system through electromagnetic wave radiation; the second is power disturbance, which directly damages the system; The third is the signal disturbance channel, which enters the system through the front and rear channels connected to the host. In order to ensure that the instrumentation ...

1. Overload maintenance failure: The circuit breaker should be tripped for maintenance when the current exceeds the rated current, but sometimes the overload maintenance failure may be due to some reasons. This may be due to incorrect overload maintenance settings, long overload periods, thermal aging due to successive overloads, etc. 2 ...
