dear all, in motor operation , motor is of 100 hp and bimetal relay setting is 130 amp, if relay is getting tripped on 120 amp balance current what can be the reason? Relay is newly replaced. I dont know but is there any frequency effect in thit case? Can frequency variation affect bimetal relay operation?

Define rise time.
a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
