Do. Koval, TRANSMISSION EQUIPMENT RELIABILITY DATA FROM CANADIAN-ELECTRICAL-ASSOCIATION, IEEE transactions on industry applications, 32(6), 1996, pp. 1431-1439
Frequent forced outages of transmission equipment can significantly af
fect the performance of industrial and commercial power systems and th
e processes they control, Historical transmission reliability data pro
vides the ability to predict the performance of various transmission l
ine configurations and assess the economic impact of forced outages on
industrial and commercial power systems, The prediction methodologies
are presented in IEEE Std, 493 (i,e,, IEEE Gold Book) [1], This paper
will present a summary of the Canadian Electrical Association's Equip
ment Reliability Information System [2], [3] statistics on the forced
outage performance characteristics of transmission equipment (i,e,, tr
ansformers, circuit breakers, cables, etc.) for Canadian utilities for
the period 1988-1992, The paper will reveal the structure of the data
base and present relevant summary data (i,e,, the frequency and durat
ion of forced outages) necessary for the application of these reliabil
ity methodologies, A knowledge of the primary causes of the major equi
pment forced outages as to whether the outages are primarily due to th
e subcomponents of the major equipment or to its terminal equipment is
essential for designing, operating and maintaining a reliable transmi
ssion system, This paper will discuss and identify for each major equi
pment the primary subcomponent (e,g,, transformer windings) and the te
rminal equipment (e,g,, auxiliary equipment) which dominated the force
d outage statistics of the major equipment for the five year period.
