6.3.1.2 Winding Currents
PATH: ACTUAL VALUES
 A2 METERING  CURRENT  W1(3) CURRENT
The fundamental frequency current magnitudes for winding 1 phases A, B, and C, neutral,
and ground are shown. The current angle for phase A is always set to 0° as it is used as
reference for all other currents, both measured and derived. The maximum specified load
and average phase current are also shown for the specified winding.
6.3.1.3 Positive-sequence Current
PATH: ACTUAL VALUES
 A2 METERING  CURRENT  POSITIVE SEQUENCE
NOTE
Note
All positive-, negative-, and zero- sequence component phase angles are referenced to
the winding 1 phase A current
The positive-sequence current magnitudes and phase values for windings 1, 2, and 3 are
shown here.
