... The effect of utility impedance on the operation of a drive is a function of how stiff or soft the line is. Nominally (i.e. %Z = 1%), the drive short circuit current is set at 100 times the drive rating. On a soft line (i.e. %Z > 10%), the short circuit rating is 10 times the drive’s rating; and on ...
