34.5 KV Breaker, Outdoor or Indoor??
34.5 KV Breaker, Outdoor or Indoor??
(OP)
Hi all:
I am doing a design for a 13.8 KV Substation.
There are six incoming lines in 13.8 KV. Two of those incoming lines will come from 34.5/13.8 KV XRF's. Besides there are 20 outgoing lines in 13.8 KV.
I want some suggestion about what kind of 34.5 KV breaker i should use: outdoor (beside the 34.5/13.8 KV XFR), or indoor (inside the switchgear room in a 34.5 KV GIS switchgear)??.
Thanks in advance

From my point of view isn't technical issue.
Price and place play here only.
Im usually prefer indoor installation.
34.5kV GIS or AIS is also price issue.
Of coutse you have take in account cables, installation,protection and metering cubicles, etc.
Best Regards.

It is very difficult to find switchgear for 200kv BIL and Arc resistant as we require. Therefore we don't use switchgear at 34.5kv.
