The connections of Metrosil Stabilizing Resistor and neural CT are shown in above figure. Earth leakage relay ELR and core balance current transformer CBCT ZCT have been widely used and accepted. Check also: earth and understand more manual guide in restricted earth fault relay connection diagram 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.
The connection of earth fault. Correct operation of transformer differential protection requires that the transformer primary and secondary currents as measured by the relay are in phase.

Non-Linear resistors are connected in parallel with the relay circuit to limit the peak voltage developed across the high impedance.
The windings of many medium and small sized transformers are protected by restricted earth fault REF systems. This relay protects the delta or unearthed star winding of the power transformer against the fault current. Because if the fault occurs outside of the zone means the same fault. As shown in figure above there are a total of four Current Transformers CTs three CTs connected in each phase ie. The secondary of these four CTs are connected in parallel. If the transformer is connected deltastar as shown in Figure 6 balanced three-phase through current suffers a phase change of 30.
