WHAT IS THE SPECIFICATIONS CONSIDERED DURING DESIGN FOR THE
OVER CURRENT RELAY?
Answer Posted / appurao. s
For the Over Current Relay, (Mostly CT operated)it will be considered the Ct secondary current either 1A or 5A depends on the system design. Mostly today's digital relays are having the option to select between the range.
Also the time for interrupting the flow of current when the over current phenomena arises. Time setting will be range bound, so that the user can decide.

A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
