VSD HarmonicsVSD driven motor feeders require thorough assessment of their entire scheme including amongst others:(i)Motor insulation system life-time impact from voltage harmonics and voltage peaks(ii)Cable length limitations(iii)Output filter requirements(iv)Motor cable additional current(v)Motor bearings lifetime impact(vi)Motor noise impact (vii)Total harmonic distortion impact on motor(viii)Total harmonic distortion impact on switchboard and plantVFD motor requirements report to be prepared and submitted to show that selection and design of motors and VSDs are coordinated
