Considerations in Protecting the Consumer-Utility Interconnection

It is essential that good protective reay applications be followed during the initil design of a utiity-consumer Interconnection. This approach will minimize operating problems that may not arise until after the interconnecton b in service. Tfie coesumer-utity guide is intended to establish a comuhon undertanding among those involved in the intertie design. Important Information requird by both the utlity and consumer are outlined. Supply and load condderations are described. Protection theory is discussed. and spedic relay application examples are covered in detail.
