This recommended practice is directed primarily to high-capacity systems (exceeding 1000 hp) and drive systems, which normally include equipments such as transformers, reactors, thyristor power converters, and synchronous machines. The method recommends that the existing test standards for the system equipments be used as reference, supplemented by test and calculations include herein to account for operating characteristics of the adjustable-speed drive systems. 517 $aANSI/IEEE Std 995-1987: IEEE Recommended Practice for Efficiency Determination of Alternating-Current Adjustable-Speed Drives.
