Power Quality
(OP)
Does anyone know where I can find a standard on power quality? I am looking for a good ANSI or IEEE definition. So far I can just find where they talk about how outages should be infrequent and limited, and where prompt corrective action shall be taken to get this corrected.
Any help will be appreciated.
Thanks

Take a look at the following: http://www.naruc.org/international/Documents/Elect...
For harmonics, jraef is right mentioning IEEE 519. IEC world uses the 61000 series of std.
Hope this will help.

For reliability indices, IEEE Std 1366 covers the material in Desrod2's link from a Naruc presentation. It is a "how to" calculate standard for the different indices like SAIDI and SAIFI. As far as outages being infrequent and limited, I don't think you'll find a standard that deals with this aspect. That's more of a regulatory issue and can be very subjective.
For the three voltages that you've listed, ANSI lists nominal system voltages of 46, 115 and 230 kV. The circuit breaker standards for these voltages assume a +/-5% tolerance with a maximum voltage of 48.3, 121 and 242 kV respectively. You can use the -5% tolerance and get the minimums, but keep in mind that would be based mainly on circuit breakers.
