Class 8839 58M Enclosed AC Drives

Three Phase Line Reactors

The Class 8839 58M Enclosed AC Drives are designed to operate from industrial power systems with normal AC line conditions without the need of additional line impedance from either an isolation transformer or a line reactor. However, when abnormal line conditions exist, additional line impedance may be required. Typically, line reactors are used to:

•Reduce the input rms current to the AC drive ratings

•Lower the available fault current on high fault distribution systems

•Limit the total harmonic voltage distortion from the AC drive at the point of common coupling to align with IEEE 519 guidelines

•Prevent AC drive nuisance tripping due to transient overvoltages from power factor correction capacitor switching
