The numbers you have mentioned are ANSI devices numbers. No I am not looking for that. The question was pertaining to standards and technical codes with reference to Gen maintenance. Regret that I was not clear enough.
Rbulsara,
I am trying to make / change schedule for maintenance - specifically electrical tests for condition monitoring purpose and looking for document that provides guidelines for the purpose - other thatn OEM manuals. Have consulted OEM manuals but they are not clear enough on the front.
Looking for best practices, Standards, Codes, regulations and any other material that is available.

daily:
check temps, pressure, purity of H2 or anything, bearing vibrations, look at collector for any arcing, seal oil system.
monthly:
perform shaft voltage testing, replace brushes as needed.
annually:
inspect general terminals for any leakage and clean bushings disconnect switches and any PT/CT if its mounted on top of the generator (GTE),
every 2 years:
minor inspection, high pot, elcid, insulation testing.
Regards,
Steve

What size generator? What is the type of prime mover? A lot dependeds on the fucntion/purpose and configuration of your plant as to what you can shutdown for maintenace and how often.
For any sizable power plant you will need to consult your counterparts or a forum consisting of power plant operators. If you are part of an established firm, there must be existing guidelines. If so, you should have very good reason to "change" them besides money and inconvenicece. OEM recommendations are a good beginning. As Zogzog said NETA-MTS is also a good place to start.
You also need to coincide the electrical maintenance with mechanical (prime mover).
