harmonic measurement and calculation
harmonic measurement and calculation
(OP)
there are some manufacturers of variable frequency drives that advertise, meeting IEEE-519, less then 5% THD on their drives. can someone please tell me where is the proper place to measure THD, the line, the neutral?
it seems to me that a typical drive will produce upwards of 30 to 40% THD, what are they doing to rectify this?
thanks in advance
Doug.
