Abstract

For pt.I see ibid., vol.112, no.1, p.134-43 (1997). Part I presented practical calculations and novel techniques for collecting performance data from protective relays. Standard definitions were presented for availability, dependability, security, hardware and relaying MTBF, and other measures. Part II gives practical guidelines and complete examples of actual data collection procedures. It focuses on methods for users to compile exposure counts needed for the novel security measurement. Also reasons for collection and uses for the statistical results are described
