Minimum distance between A and B Batteries
Minimum distance between A and B Batteries
(OP)
138kV substation with 125 VDC battery A and battery B for protection A and B, trip coil 1 and trip coil 2, etc.
The distance between two batteries is about 5 feet.
I commented too close but have not find any reference to prove my feeling.
Could you please help to enlighten me on this by providing some standards?
Thank you,

Five feet seems small. Maybe adding a barrier between the two batteries to prevent a common fire damage or adding fire suppression in the room would create the same reliability.

Common sense, experience and apply good engineering practice could be used for engineeing judgement to avoid single point of failure.
A balance between cost, safety and system reliability should be considered.
I hope this help.

I'm a protection and controls engineer (like yourself) with HydroOne Networks, the main utility in Ontario.

Separate building it's really extreme.
Are you talking about A,B protection systems or battery or about both?

I haven't seen some standard/code requirement, these rules are just common sense and practice.

It may be like this in theory and practice, but in real life it is completely different.

Yes i know it is extreme. And yes I am talking about both.
This is a new initiative, and has yet to be implimented (as far as I know). We look after hundreds of stations so I can't speak for them all. I do know there are plans to start putting this into action.
Personally, I think it does make sense, but it is at a huge cost. I think it is being done here because more and more private companies are getting into the generating market. There is more pressure on us (as the public utility) to make sure these guys can sell their power 24/7. I can only imagaine there is a heavy political influence too, but I tend to stay away from those conversations as I am already losing my hair faster than I want.

If it's start in one place...., after few years we'll see it
as standard in many companies and countries.
bay the way isn't so strange.
Very intresting !!!!!!!!!!!
