Is there a voltage phase shift through every transformer? If that is the case then in the case of a potential transformer, how does a relay know exactly where on the primary voltage waveform it is, if there is a voltage phase shift between the primary and secondary side of a potential transformer providing an input to an feeder protection relay?
An example I am referencing is a 4160V to 120V potential transformer providing an voltage input/reference to a multilin feeder protection relay.
