- Analyzing and Minimizing Distribution System Harmonic and Transient Disturbances
Analyzing and Minimizing Distribution System Harmonic and Transient Disturbances
Learn about the harmonic and transient disturbance categories and standards, and how to recognize and analyze them. Case studies, and representative waveforms for commercial, industrial, and utility facilities will be featured, along with wind plant and renewable energy course examples.
Practice Area: Power
Overview
What are Harmonic and Transient Disturbances?
Voltage disturbances can occur on electric power distribution systems that feed industrial plants, large commercial facilities, and residential neighborhoods. These disturbances can be transient impulses (lasting less than a few milliseconds), short-duration sags or swells (lasting between a few milliseconds and 1 minute), or they can be long term, repeating waveform distortion (harmonics). Even if they don’t cause immediate outages, over time these disturbances can lead to mis-operation of sensitive facility loads or reduce the operating life of equipment.
Who should attend?
- Electric utility engineers involved in distribution engineering, operations, or planning
- Electric utility customer service engineers
- Engineering technicians
- Electrical contractors for C&I customers
- Distributed renewable generation engineers
- Drive manufacturers and vendors
