Switchgear Circuit Breakers
Switchgear Circuit Breakers
(OP)
Hi All,
I'm adding four(4) new, 15kV metal-clad switchgear breakers to an existing line-up. I plan to utilize DC power for the tripping, closing, spring-charging and protective relay. Now, my concern is whether the existing battery cells have the adequate capacity (i.e. battery voltage)to provide what I need.
What should I do to ensure or how do I make a check if the battery cells have the some spare capacity for my application.
Appreciate your inputs.

RE: Switchgear Circuit Breakers
Figure out how much capacity you currently use or need to have to hold in reserve. (what loads you have currently and how many time you want to be able to operate them and for how long)
Figure out how much capacity you will add. (what load you will add and how long they will need to operate or how many times)
Do the math.
Test the batteries if needed if there is some reason to believe that they are weak.

There is more to it than you might initially consider, although it is not that complicated to work through.
