Iwould like to know barc interview questions
why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?
I have doubt that the supply HZ (very low or high than rated ) may affect the power factor. is it true. ?
how do we calculate length of starting time and repeated starting of a direct online starter?
