Working of Static Relay
The primary of C.T. is connected to transmission line and secondary is connected to some filter circuit. This filtered signal is given to rectifier where it is converted from AC into DC (Electronics equipments works on
Microprocessor Based Overcurrent Relay
Current is taken from C.T. and given to I to V converter because many electronics circuit require voltage signal for operation. The A.C. voltage is converted into D.C. voltage by using rectifier. This D.C. voltage is proportional
Difference between static relays and electromagnetic relays
Points Static Relays Electromagnetic Relays Power consumption Very less 1 milliwatt High 2 watt Moving contacts No moving contacts. So, No problem of Arcing No needs to replace contacts. Moving contacts are present. Problem like Arcing, Replacement
