CHAPTER 5: SETTINGS
In our example, the following phase and zero-sequence compensation equations would be used:
For Winding 1:
For Winding 2:
5.5.4.7 Magnitude, phase, angle, and zero-sequence compensation calculations
Complete magnitude, phase angle, and zero sequence compensation is as follows:
where
c c c
I [w], I [w], and I [w] = magnitude, phase, and zero-sequence compensated winding w phase currents
A B C
M [w] = magnitude compensation factor for winding w (see previous sections)
p c c
I [w], I [w], and I [w] = phase and zero sequence compensated winding w phase currents (see earlier)

c p
I [w] = M [w] x I [w], where w = 1, 2
A A
c p
I [w] = M [w] x I [w], where w = 1, 2
