High-availability power systems: Redundancy options

In major applications like major computer installations, process control in chemical plants, safety monitors, IC units of hospitals etc., even a temporary power failure may lead to large economic losses. For such critical loads, it is of paramount importance to use UPS systems.

But all UPS equipments should be completely de-energized for preventive maintenance at least once per year. This limits the availability of the power system. Now there a ....etc

ABSTRACT
Almost all firms use UPS systems. They maintain the continuity of supply in case of power outages. But all UPS equipments regardless of manufacturer should be completely de-energized for preventive maintenance at least once per year. This limits the availability of the power system.
But now-a “days certain configurations of the UPS systems are there to permit concurrent maintenance so that we can overcome the above problem.

But all UPS equipments should be completely de-energized for preventive maintenance at least once per year. This limits the availability of the power system. Now there are new UPS systems in the market to permit concurrent maintenance.
