Abstract :
Thispaperpresents an analysis of reliability and Life
Cycle Costs of two different schemes; a single busbar in two sections
and a double circuit breaker system With double busbus. TWO main
questions initiated this study: 1. Do the substations have a design of
uniform strength regarding the reliability of included components
and sub-systems or is there unnecessary redundancy or weakpoints.
2. Can improvements of reliability and availability of the components
during the last decades be taken as a justification for simpli3-
cation of sub-station schemes.
