I'm involved in the selection of VFD's for some large AC motors (up to 450HP). The spec that was given to the supplier imposes the requirement that these VFD's "shall meet all requirements of IEEE Std 519".
I have IEEE Std 519 ("Recommended Practices and Requirements for Harmonic Control in Elect Power Systems"), and have read through it. But I do not see "requirements"; it seems to be nothing more than suggested guidelines.
So, what is there in IEEE Std 519 that can be considered to be REQUIREMENTS?
