Ferroresonant constant AC voltage transformer

摘要: Primary and secondary windings of each transformer in a three-phase system form pair independent windings, the first winding primary pairs formed on iron core one transformers second adjacent thereto are connected series to other. These serially regarded as phase respectively, they other either delta connection or Y connection. A variation voltage caused by change load current outputs has an influence not only at that output but also voltages consequently enables deviation difference between due loss balance be decreased about half. When leg parts two cores juxtaposed common is so may function equivalently series, number required all half where independently cores.
