Highlights the importance of power quality and the integrity of critical loads, even when a short circuit occurs on the load side. Examines the inherent complexities of parallel redundant uninterruptible power supply (ups) systems and the paradox of internal or external static switches. Recommends that, when integral internal static switches are part of a parallel redundant system, a careful study is made of the input side circuit breakers to avoid a break in the supply. Advocates an external static switch, with a parallel redundant system, to maintain 99.999% power availability.
