Hi everyone
I have two questions
1: How do I determine the load current of a 6.6kV, 2MW 4 pole AC motor
2: Can anyone suggest good motor protection relays for this type of motor
Thanks in advance for your help

The Full Load Amps (FLA) are on the nameplate. Are you asking for specific manufacturer's of motor protection relays or a general scheme of protection?
A good place to start is IEEE 242 (Buff Book) Chapter 9, Motor Protection.

Brand recommendations are to be avoided in this forum unless specifically requested, and as wbd pointed out your request is a little vague as to whether you wanted brands or ideas.
