Angle between the phase currents for each end of the transformer
●
Angle between the currents of the same phase between two ends of the
transformer
●
Angle between the derived residual current and the current measured at
the transformer -Tx4 (see Section 5.7, (p. 5-22)) for each end of the
transformer
