Sound Mitigation For Air Core Reactors
Abstract: +An air core reactor (47) including a plurality of concentric conductor winding packages (44 46) wherein a force (F) generated by the interaction of current (+) flowing through one package and a magnetic field (42) generated by the reactor is out of phase (F ) with a force generated in another package thereby effectively mitigating audible sound generated by power operation of the reactor. In one embodiment (FIG. 3) the out of phase force may be generated when at least one winding (38c 38d) of one package (38) is configured to conduct a current ( ) that is at least 10 degrees out of phase with a current (+) conducted by another package (40) or other windings (38a 38b) of the reactor (36).
