Background

Status: Approved
Date Posted: Mar 26, 2010
Sponsor: SPWG
Urgent: No
Sections: 6.1.2.3, 6.1.2.4
Description: This Nodal Operating Guide Revision Request (NOGRR) synchronizes the Nodal Operating Guides with OGRR243 by changing data recording and reporting requirements for equipment operating at 100kV or above at Facilities where fault recording equipment is required.
Reason: The System Protection Working Group (SPWG) prefers that the fault data recording requirements allow for calculated electrical quantities which are used in modern protection system equipment and can be determined by modern fault analysis software. The SPWG also prefers that recording requirements for autotransformers should allow for monitoring of either high voltage or low voltage terminals and that specification in the fault reporting template of the recorded time standard (such as Central Standard Time (CST) or Coordinated Universal Time (UTC)), replace the requirement of CST recording requirements.
