Outdoor Disconnect Switch
Outdoor Disconnect Switch
(OP)
Hi there,
A quick question on disconnect switch. Can we utilize a 25kv outdoor disconnect switch on an existing 13.8kV line ? I know that 13.8kV disconnect switch exists but the client had purchased a 25kv disconnect switch instead.
Want some thoughts on that..

I'm in Canada. The ratings (i.e continuous rating (900A) & mom.asymmetrical (40kA))for the 13.8 and 25kv outdoor disconnect switch is the same. I'm under the impression that a 25kV outdoor disconnect switch can be used on an exiting 13.8kV line but would just like to get some clarifications.
Note that this is an outdoor application on a riser pole.
Thank you..Sonic

Conversion was usually done over a number of years (3-5 year). New network sections would have been built as at 25 kV naturally.
With proper ratings, there is usually no problem as mentioned by David.

Check if there is not issues with electrical clearances or other constains.
