Does the 8839MFD meet IEEE519 requirement?

Issue:
8839MFD  IEEE519 requirement

Product Line:
ALTIVAR 61

Environment:
All
 
Cause:
Requirement

Resolution:
You would need a harmonic study. The M-flex (or any 6 pulse drive) would probably not  meet IEEE519 with just a line reactor. However, since the harmonic noise is to be measured at the point of common coupling, which is the primary of the transformer from which the drive is powered, there is no way to be sure without actually doing the measurement as the transformer itself will filter much of this noise out. A passive filter (such as the matrix filter) on a 6 pulse drive, or the 18 pulse drive would probably meet IEEE519, but again would have to be measured for confirmation. It depends on the power system in question.
