A harmonic mitigating device connected between the power distribution system and the load provides a flux shifting multiple-winding reactor with, a capacitor bank connected between the reactor windings. At least one line winding is, oriented in a first polarity on a core and at least one compensating winding oriented, in the opposite polarity on the core and connected between the output of the first, winding and the load. The opposing fluxes generated by the line winding and the, compensating winding cancel and thus reduce the through-reactance of the device, between the load and the power supply. The input of a cross-link circuit comprising a, capacitor is connected between the line …

Why it's free to use
- Filed April 9, 1999 and granted June 19, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 9, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 9, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
