You will come to know the reason. Since 100 A of current is flowing in winding PN of star side, therefore, the current in corresponding delta side of winding AB will also be 100 A as voltage ratio is assumed unity. Why? In Star Star transformer we may or may not need this filtering but it is recommended to enable this. This concept is useful in Transformer having earthed Star winding.

This will create an imbalance in the differential current and may lead to actuation of Differential Relay even in through fault condition.

Prev: Basic working principle of longitudinal differential protection of generator, Next: Zero sequence current protection principle, Copyright 2014, following Paul Business Network Shanghai ICP 11009447-2, Basic working principle of longitudinal differential protection of generator, Zero sequence current protection principle. Therefore if filtering is enabled, then relay input for differential calculation will be (100 – x) A in Star side of Transformer and that in Delta side is (100 – x) A. What is the Need for Zero Sequence Filtering? As zero sequence current cannot flow in Delta side, therefore line current IA – IB will not have any zero sequence current components and hence line CTs secondary currents I1, I2 and I3 won’t also have no zero sequence current component. In case of single line to ground fault in STAR side, fault current in line will contain zero sequence current component but due to DELTA connection of CTs, this zero sequence current will circulate around the DELTA loop. Next you might ask why we didn’t connect these CTs in delta?

Actually in differential protection of Transformer we need to correct the phase as there is a phase change of 30 °in currents from Delta to Star, therefore to match the phase, we connected CTs in STAR fashion. 10/1A) zero sequence CT as CT saturation is not a concern if regular earth fault protection is implemented using the phase CTs. Our biased differential relay is an old static relay which has interposing CT (ICT) on both side. The fault current in the example was 100 A. Take IR of tranaformer and bus bar. Let us understand the above expiation with some numeric data. CTs in Delta side of Transformer are connected in STAR while that in STAR side, it is connected in Delta.
