How to Perform a UPS Transfer in a Critical Data Center

The Markley Group demonstrates how power at a UPS in a data center is transferred without its critical loads seeing any interruption. Routinely this type of procedure is performed at One Summer Street to allow technicians to safely work on critical electrical equipment without any risk to your information.

    Looking at your schematic drawing I would ask why do you put you it load at risk and run on generator raw power when you could isolate one ups system to work on and use the second ups system to power the load and maintain ups support to your it load . As a data Center I would expect you to have a minimum off N+1. So 1 ups should be able to take the load .
    This is something that I do as a regular switching operation for ups maintenance.

    I don’t even own a critical data centre but when I do, i’ll know what to do

    As ups enginner this kind of job is very critical.
    The easiest way to fired you? Just cut of the load!!!

    This can use DRUPS to make thing easier, it is automatically transfer u power and normally transfer to gen set power within few seconds.

    That is some out of date equipment by today’s standards

    What kind of suit is that at 1:24?

    I have concerns about running IT loads with a generator with no UPS in between. IT has a pretty big leading power factor while a generator has a relatively low lagging power factor. In theory, couldn’t this trip off the generator?

    Why can’t i pause this to take notes…..

    Sir why utility power is change over to DG?

  17. robinvannoor on April 13, 2021 at 12:43 am

    Is there down time when moving load from second UPS to the static bypass?

    WHAT IS THE MAX ELECTRICAL POWER CAN SUPPLY FROM UPS AND CAN WE OPERATE CHILLERS 800 KVA AND IF POSSIBLE FOR HOW MANY MINUTS OR HOURS .THANKS
