Relay Circuit Diagram And Operation. The output of ct and pt are not suitable for static components so they are brought down to suitable level by auxiliary ct and pt. A 230v ac supply is provided to the load in this case the load is represented with a lamp.
Terms related to relay energizing. When current starts flowing through the control coil the electromagnet starts energizing and thus intensifies the magnetic field. It will continue downward as you will see later on.
Then auxiliary ct output is given to rectifier.
Then auxiliary ct output is given to rectifier. There you have it. Relay is a switch which senses fault in a system and once fault is sensed by the relay it issues trip command to the circuit breaker cb to isolate the faulty section of the network from the healthy section. Then auxiliary ct output is given to rectifier.
