HV Swichboards Reliability Data 1

[veritas]

Hi

Can anyone provide any data with respect to failure rates of 22kV indoor switchboards please? I am interested in any study or published data regarding failure rates of HV swbds, i.e. number of failures per swbd per year, etc.

Thanks.

See [for instance]:
IEEE Standard 493-1997, IEEE Recommended Practice for Design of Reliable Industrial and Commercial Power Systems
I am not sure if this is it what you actually search for. However could be interesting. See:

Interesting reading indeed, not quite what I was looking for but informative nevertheless. Thanks.
