Step 1. Phasor rotation is as expected.

Step 2. Circle your transformer and CT connection:

If E87 = G, OR

If E87 = T AND

TRCON = GEN, CTCON = Y

TRCON = DABY, CTCON = DAB

TRCON = YDAB, CTCON = Y

TRCON = DACY, CTCON = DAC

TRCON = YDAC, CTCON = Y

TRCON = DABDAB, CTCON = Y

TRCON = DACDAC, CTCON = Y

TRCON = YY, CTCON = Y

Then, phase angles should be 180° apart.

Plot Phasors

If E87 = T AND

TRCON = GEN, CTCON = DAC

TRCON = DABY, CTCON = Y

TRCON = YDAC, CTCON = Y

Then, I87 should lead IW1 by 150°.

If E87 = T AND

TRCON = GEN, CTCON = DAB

TRCON = DACY, CTCON = Y

TRCON = YDAB, CTCON = Y

Then, I87 should lag IW1 by 150°.
