Answer / dilip
for dc motor Ia = (V-Eb)Ra = (735.5*H.P)/V
for 3-ph motor Ia = (735.5*H.P)/V

Reason of secondary of ct always short
Dear All, In a 400V power system, ratio of three current transformers installed incoming switchgear is 4000/1. Maximum three phases short circuit current of this system is 48kA. One CT is installed on neutral of upstream transformer (6/0.42kV, solidly earthed) for 51G protection. Would you please inform me about the correct CT ratio of this current transformer (on neutral)?? Thanks a million
