IEEE Approved Draft Recommended Practice for Conducting Motor-Starting Studies in Industrial and Commercial Power Systems

This recommended practice describes how to conduct motor-starting studies including design considerations for new systems, analytical studies for existing systems as well as operational and model validation considerations for industrial and commercial power systems. Motor starting analysis includes motor starting current and voltage drop evaluation. Accuracy of calculation results primarily relies on system modeling assumptions and methods used. This recommended practice emphasizes the use of computer-aided analysis software with a list of desirable capabilities recommended to conduct a modern motor starting study. It also presents examples of system data requirements and presents result analysis techniques. This standard discusses benefits obtained from motor-starting studies and examines various types of computer-aided motor-starting studies. Data or information required for these studies as well as the expected results of a motor-starting study effort are also reviewed.
