For each monitored winding, the fundamental frequency magnitude and phase angle
of phase A, B, C and ground currents are recalculated every half-cycle for use in
differential and overcurrent protection. From these values, neutral, positive,
negative and zero-sequence as well as differential, restraint and ground differential
currents are calculated. These are displayed and updated approximately twice a
second for readability.
