Transformer Room Design and MV switch gear etc
(OP)
Hi, I am looking for a standard or guidance note covering the need for trenches or bund walls to mitigate against oil spilage and fire risk?
The local authority here only have approved designs for substations that are externally facing, in this case I have a client owned substation which is internal to the building, and I am worried about a tank rupture and subsequent spread of oil to other parts of the building and the associated fire risk?
The local authority do not seem concerned and have said it is not required, but I think it is. So looking for some guidance or typical details?
also wondering if (aside from good practice) there is any actual requirement for separation of rooms for LV switch/ TX / MV switch - or combination thereof
Thanks

MV switchgear, transformer and LV switchboard are often segregated in order to restrict access to staff who are trained and authorised to work on a particular item of plant. However, in a utility environment it's quite common to have all three in the same room, and there's no technical reason why they can't be. Again, check the local codes.

The same issue goes for oil filled switchgear, after a relatively recent incident in Australia where oil filled switchgear suffered an internal failure during switching, a lot of places are either removing it, or putting procedures in place that the units can no longer be used for their original intended purpose (i.e. isolation of certain pieces of plant as an example).
However, if local codes don't require it, there's a lot of expense that can be involved to include it, and the client may not want to pay for it, unfortunately.
