Choosing an external resistance for an IFC short

Updated on Mon, 2021-11-15 16:55. Originally created by genevb on 2021-11-15 16:36. Under:
It is clear that when a field cage short is close to the endcap, it is best to add an external resistance to compensate for the amount of the missing resistance from the short as that would restore th
