Find, Fix, Track and Report, Docket No. RC12-2 (November 30, 2011)
Reliability Standard: TOP-004-2
Requirement: R1
Region: FRCC
Issue: FFT Entity self-reported that on one day it did not operate within the Interconnection Reliability Limits and System Operating Limits due to a failed static wire causing an outage of two 138 kV transmission lines, which then apparently led to MVA limit conditions on a 230/138 kV autotransformer.
Finding: The issue posed only a minimal risk and did not pose a serious or substantial risk to the reliability of the BPS because any loss of load would have only affected loss of local internal load. Also, even though there was an indicated overload on the autotransformer, due primarily to cold weather, the autotransformer was never actually overloaded.
