Published by Electrotek Concepts, Inc., PQSoft Case Study: Distribution Feeder Energizing, Document ID: PQS0711, Date: October 15, 2007. Abstract: The energization transients for distribution feeders are generally a combination of line energizing, transformer inrush, and load inrush. Line energizing transients typically decay to negligible values in about one-half cycle and they generally do not pose significantContinue reading “Distribution Feeder Energizing”
