ity is limited by the requirement to adequately protect the transmission line, set the transmission line distance relays to a maximum of 125% of the apparent impedance (at the impedance angle of the transmission line) subject to the follow...
AI summary The text outlines technical requirements for setting relay parameters and circuit capabilities in transmission systems, including maximum torque angles, relay loadability evaluations, and agreement requirements among stakeholders. It references IEEE standards for transformer design and temperature limits.
F. Supplemental Technical Reference Document 1. The following document is an explanatory supplement to the standard. It provides the technical rationale underlying the requirements in this standard. The reference document contains methodol...
AI summary This supplemental technical reference document explains the technical rationale behind standard requirements, providing methodology examples for determining practical relaying loadability ratings. It cites a 2007 NERC Planning Committee report as a reference, emphasizing that other comparable methodologies are not excluded.
