Transformer Differential Settings: Transformers are critical substation components that need sensitive protection. Relay protection for transformers involves calculations for differential current thresholds, through-fault stability, inrush restraint, and harmonic filtering to. There are three independent REF elements in the SEL-487E Transformer Protection Relay. The SEL-387E Current Diferential and Voltage Relay and SEL-387 Current Diferential and Overcurrent Relay come standard with an REF element, while this is an optional feature with the SEL-387A Current Diferential. Failures in transformers can be classified into: ABB's transformer protection relays are used for protection, control, mea...
