WebOct 2, 2013 · In a wye connected HRG system, intermittent faults that cause so much trouble in ungrounded systems will be eliminated by the neutral system ground resistor because its insertion limits the total current flow to ground. System continuity is maintained because, although ground fault alarms occur, the overcurrent devices do not operate. Webwye - delta connection: a.) are affected by unbalanced loads and faults to a greater extent than other three - phase connections. b.) are never affected by unbalanced loads. c.) may use a floating wye - tie if procedures call for it. d.) both A and C e.) both B and C
