How do we measure earth fault current in Generator Transformer(20/420kv),Station Transformer(20/11 kv) and Unit Transformers(20/11kv) for our plant system, since these don't have any Neutral earth Fault relay connected to their Neutral Earth? But for Unit Service transformers(11/.433 Kv) we have an Earth Fault Relay connected to its neutral earth.Why is such so?
