possibly just distortion and pulsed waveforms depends on the meters measurement method how accurate it may or may not be. with homebrew 3 phase I wonder how accurate the phases are (not voltages) is all the work being done by a couple of phases due to another lagging/leading etc if the drive has active rectification and is using one as a reference the others could be out of phase so the voltage at the instant of switching is not ideal time to scope the three phases (storage scope of all three would be best if possible) Dave ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
