Granted, harmonics in electrical systems have caused unforeseen problems. But overly cautious consultants insist on load-side harmonics mitigation devices even when they are not technically necessary and not economically justified. IEEE519 relates to electrical systems, while variable speed drives are just individual pieces in commercial building HVAC/R. This session provides practical guidance for applications of non-linear loads that are grid-operated and loads that are running off standby power supplies. Examples of reliable, economical, standard 6-pulse inverter drives will be contrasted against cases that should employ low harmonic drives. Case studies of large buildings are included. The session teaches about cost avoidance without jeopardized electrical performance. Specifying engineers will gain assurance for their variable speed drive selections in new construction. Facilities engineers will benefit from hearing about the most suitable remedies in retrofit situations.
