Ea. Udren et al., PROPOSED STATISTICAL PERFORMANCE-MEASURES FOR MICROPROCESSOR-BASED TRANSMISSION-LINE PROTECTIVE RELAYS .2. COLLECTION AND USES OF DATA, IEEE transactions on power delivery, 12(1), 1997, pp. 144-156
A preceding companion paper, Part I - Explanation of the Statistics, p
resented practical calculations and novel techniques for collecting pe
rformance data from protective relays. Standard definitions were prese
nted for Availability, Dependability, Security, Hardware and Relaying
MTBF, and other measures. The present paper gives practical guidelines
and complete examples of actual data collection procedures. It focuse
s on methods for users to compile exposure counts needed for the novel
Security measurement. Also reasons for collection and uses for the st
atistical results are described.
