The windings of many medium and small sized transformers are protected by restricted earth fault REF systems.
Then common terminals are connected to the secondary of a Neutral Current Transformer or NCT. If the residual current is calculated the first group T1T2T3 shall be specified for the inputs of the three-phase current. In Block diagram. Earth leakage relay ELR and core balance current transformer CBCT ZCT have been widely used and accepted. Restricted earth fault is to detect earth faults in the zone from secondary winding to Secondary CTs. The restricted earth-fault stage operates exclusively on earth faults inside the area of protection.

The main earth-fault protection is provided by the restricted earth-fault current stage I0 which operates instantaneously when the dif-ferential current exceeds the set start value of the restricted earth-fault stage. It is Voltage Limiting Non-Linear Resistor. The connection of earth fault.
Here is all you need to know about restricted earth fault relay connection diagram Also in through fault relay should not operate. Earth Leakage Relay ELR transmits a signal to activate the trip coil of the MCCBACBOCB CONTACTOR in the event of Earth leakage resulting in automatic isolation of the electrical power system. The main earth-fault protection is provided by the restricted earth-fault current stage I0 which operates instantaneously when the dif-ferential current exceeds the set start value of the restricted earth-fault stage.
