REF protection for Transformer LV windings
REF protection for Transformer LV windings
(OP)
High impedance REF protection for 415V windings of transformers can be two types - 5-CT scheme and 4-CT scheme.
I wonder why anye vendor should prefer 5-CT scheme to 4-CT scheme. User point of view, 5-CT scheme is more expensive and less sensitive.
Any thoughts!
