What is the condition for Phase Loss Fault in EOCR-i3DM (Z, S, 420) / iFDM (Z, S, 420)

Phase loss fault comes into play in EOCR-i3DM (Z, S, 420) / iFDM (Z, S, 420) when max imbalance is more than 85% among 3 phase current.

Where,Imbalance factor (%) = (Imax phase - Imin_phase) / Imax_phase x 100%
