This guide contains information on a number of different protective relaying practices for the utility-consumer interconnection. It is intended to cover applications involving service to a consumer that normally requires a transformation between the utility's supply voltage and the consumer's utilization voltage. Interconnections supplied at the utilization voltage are not covered. This guide is not intended to supplant specific utility or consumer practices, procedures, requirements, or any contractual agreement between the utility and consumer. The examples of interconnection protection of varying complexities that have been provided are used for illustrative purpose only and do not necessarily represent the preferred protection under all conditions. This guide addresses consumers, with or without conventional generation, that are connected to utility subtransmission or transmission circuits. The specific control schemes associated with generation are not addressed. It is not intended to apply to consumer generation connected to utility distribution circuits. For these interconnections, refer to IEEE Std 1547(TM)-2003.

The scope of this guide does not include the subject of lightning protection for electrical systems as provided by shielding or lightning arrester devices. Lightning is, of course, often the cause of short circuits on power systems, but only the clearing of these short circuits through the use of protective devices is within the scope of this guide.
