Call of the Month for October 2008

Via EPRI's PQ Knowledge (PQK) Power Quality Hotline, a PQK funder asked EPRI engineers to provide information about applying line reactors to adjustable-speed drives (ASDs) and whether line reactors were really necessary. The PQK funder wanted to better understand the significance of these devices and what they actually accomplish.
