Keeping the power on in healthcare facilities can be a matter of life and death. according to an article on the Engineer Live website.
Having a standby power supply in the form of batteries, generating-sets or a combination of the two is essential.
A battery-powered uninterruptible power supply can instantaneously take over if the regular power supply fails. There would also normally be a diesel generator that runs for as long as there is a fuel source. Its purpose is to take over as medium-term supply once the battery has managed the immediate problem.
Supplying sufficient fuel for the generator to run for an extended period is the first and most basic requirement. Installing and testing a fixed load bank to the backup generator improves the likelihood of it running efficiently in the event of a power emergency.
