Reliabilty and interrupted energy rate evaluation for electrical system based on Tier classification

Abstract

This paper presents the method to evaluate the reliability and interrupted energy rate for the high reliable electrical system. The evaluated system is the petrochemical plant system designed based on Tier classification that is a criterion to address a reliability level of electrical and mechanical infrastructure of the data center. This paper modifies the system to the different infrastructure for cost reduction. Then, both actual and modified systems are evaluated. The evaluated results show reliability indices and interrupted energy rates of both systems. These indices help comparing both systems that can guide for system design.
