Required to fully understand the operating principle of the electrical control circuit and working process

Relay contactor control system failure is common, to quickly and accurately determine the cause of failure, nature and location (point). This requires full understanding of the operation of the electrical control circuit principle and working process.  Voltage stabilizer  the practice followed by the gradual accumulation of experience, lessons learned, improve the technical level. The general nature of the fault can be broadly  mcb circuit breaker  categories: the first air circuit breaker  electrical component fails, the failure of this nature is easier to find. The second category mostly wiring error, or break, hitting lines and damaged insulation. Such failures occurred, often caused by electrical components malfunction or no action.
