Answer / raj patel

star connection eliminate multiple of 3 harmonics because of its phase sum at that point makes it zero. and same case for delta connected winding it is that phasor sum of current for multiple of 3 harmonics get zero. So without any special arrangement it is inherent capability of star and delta connection to eliminate harmonics that are multiple of 3.

is KVAR (not reverse power) relay necessary to protect from excitor field failure on a brushless, synchroneus generator? Some people with previos experince tell me no but the manufacturers tell me it is designed for that purpose. Is it that it is only necessary for brushless generators and not the older style with the slip rings and brushes?
