Motor starting time
Motor starting time
(OP)
I am doing a dynamic motor starting study for 5000HP motor using ETAP.
Based on motor data,load data, motor innertia(1130),coupling inertia(25), load inertia(78), the starting time is only 3seconds. Based on my experience, it should be at least 5s. is there something wrong with my inputs? Or maybe the load inertia( I assumed ) is too low.

Also, did you consider it an infinite bus? Voltage drop will affect starting time.

As do occasionally inebriated minds like ours eh?!
