Motor Starting ETAP

[iam3NG]

Dear All,

I have problem with motor starting on ETAP. Anybody can help me with detail and comparison of DOL, D-Y starter, softstarter on ETAP please?

I think ETAP models them as same as in motor starting theory. Actually, you can refer to the help file as you start to choose your starting device. DOL and Y-D starting are same as in theory. Softstarters, however, you have to be specific what type of starter it is. The only goal is, as a softstarter, is to limit current upon starting of motors, you will have to chose from the list.

Thank you Sir, but the result is confusing. When i use DOL, the voltage 88% but. and when i use current limit the result was same. Any detail for fill the etap data?
I follow etap help as guidance.

By the way, what kind of motor starting are we talking about here? Static or dynamic? So that we know where we could start on the lacking data.

This is the good question, because i don't know to what the difference. I tried both of them at etap. Please kindly help me.

If you really want to know the motor's acceleration time with torque-load modeling to the load of the motors, you are doing a motor dynamic study. If you only at least know the voltage dip without knowing the acceleration time(maybe) then static simulation is enough. You can check it in the motor's properties.
