Abstract
A cascading tap changing regulator has a set of input taps to power both stages of the cascade, each stage having its own series injection transformer to regulate the output. A set of switches are selectively engagable in respective on-off modes to effect a number of regulation steps, and a ratio of the number of steps to the number of switches in the set is greater than 1:1.
Claims3
A tap changing regulator comprising a plurality of regulator stages disposed in series cascade, and
- a set of input taps for each stage of the cascade, each stage having its own series injection transformer to regulate an output;
- a set of switches in a first regulator stage, the set of switches comprising a number of switches that are selectively engageable in respective on-off modes to effect a number of regulation steps in the first regulator stage;
- wherein a ratio of the number of regulation steps to the number of switches in the set of switches in the stage is greater than 1:1.
