Note: The above coefficients can be derived with the following equations:
(1) Currents in three-phase (I L1 , I L2 , I L3 ) and in symmetrical component (I1, I2, I0):
where,
For example, in In=1A , we can have coefficient 1706.666667.
(2) Earth fault current (I e ) and I e used for SEF (I se ) :
where,
