Hospital Power System

Ruggedscot:

With a hospital you are looking to keep the power going for as long as possible and ensure that there is duplicity in the critical areas so that a supply can be pretty much depended upon, actually its the post op care areas and the ICU that really need the power as these areas that individual is not being baby sat like they are in the theatre. if the power goes down you better hope that there is back up on the equipment just to ride through until the staff can get a grasp on all thats going on.


So in a hospital you have an electrical supply, this supply is backed up by a generator or generators depending on the site load requirements. Also if you are applying n+1 then this has to be considered with the generators.


So this supply is provided to the hospital - you have the risk when the supply fails of a delay in power till the generators kick in so you cover that with a UPS to provide fill in between utility and generator.


So this UPS back up is used to supply all the critical equipment on site. You will have a UPS system installed that can cover the electrical system and ensure that there is no risk from a single point of failure. Generally you would specify two UPS systems on an n+1 layout so that if one UPS fails the other can keep the system going. This would be kept seperate and the wiring seperated as well to ensure that a source of power is available to the protected equipment. The biggest fear being a single point of failure affecting the critical areas. 


An additional type of supply is provided to a hospital which is an isolated power supply This is a supp,y that is un referenced to earth. This means that the wiring or equipment could have an insulation failure but it will allow that item to keep going and would alarm to let the staff know to take action. it provides a further degree of protection. In addition to that there would be interweaving of the supplies in and around these critical areas to ensure that in the vent of a loss of one supply it would not affect the other supply. 


simple really and all about ensuring that the patient electrical supplies are kept well protected.
