DOI: 10.1109/mias.2017.2740441
Abstract: Large engineered adjustable-speed-drive (ASD) systems are typically rated above 7 kV, with 5,000 or 10,000 hp considered engineered products and systems (i.e., one-of-a-kind or one-off designs) as opposed to off-the-shelf equipment. As such, they require… read more here.
