Abstract
Abstract A system and method for regulating the voltage from a threephase delta-connected source to a three-phase delta-connected load circuit that includes a voltage regulator for each phase with the input to each regulator being made to be conductively independent of the other phases, while the outputs of the regulators are interconnected into a three-phase delta connection with each regulator thereby being essentially unaffected by the power controlled in the other phases.

Claim 1
Independent Claim
102 words
A system for regulating the value of voltage from a threephase delta-connected source to a three-phase delta-connected load circuit comprising means connected to the source for providing three source outputs, each of said source outputs consisting of only one phase of the source and being conductively independent of each other, three distinct regulating means with each having an input and an output and functioning to maintain a constant value of voltage at its output, means connecting each regulating means to only one source output and means connecting the outputs of the regulators together in a three-phase delta connection to the load circuit.
Claim 2
Independent Claim
102 words
A system for regulating the value of voltage from a threephase delta-connected source to a three-phase delta-connected load circuit comprising means connected to the source for providing three source outputs, each of said source outputs consisting of only one phase of the source and being conductively independent of each other, three distinct regulating means with each having an input and an output and functioning to maintain a constant value of voltage at its output, means connecting each regulating means to only one source output and means connecting the outputs of the regulators together in a three-phase delta connection to the load circuit.
Claim 3
Dependent Claim
60 words
The invention as defined in claim 1 in which the output of each regulating means includes a first and a second output terminal and in which the means interconnecting the output terminals interconnects the second terminal of one regulating means to the first terminal of another regulating means with the first terminals supplying the delta-connected power to the load circuit.
Claim 4
Dependent Claim
37 words
The invention as defined in claim 2 in which each regulating means includes a pair of input terminals and in which one input terminal of each regulating means is connected to be common with one output terminal.
Claim 5
Dependent Claim
32 words
The invention as defined in claim 3 in which each regulator includes means for providing a regulating voltage and in which said means is interconnected between the other input and output terminals.
Claim 6
Dependent Claim
51 words
The invention as defined in claim 1 in which each of said regulating means has a pair of input terminals, in which each source output consists of a pair of leads and in which the leads of one source output are only connected to the input terminals of one regulating means.
Claim 7
Dependent Claim
52 words
The invention as defined in claim 1 in which the means for providing the source outputs includes a transformer having three distinct primary and secondary windings, means connecting the primary windings in a three-phase delta configuration and to the three-phase delta-connected source, and in which each secondary winding provides a source output.
Claim 8
Dependent Claim
44 words
The invention as defined in claim 6 in which the input of each regulating means includes two terminals and in which the means connecting each regulating means to a source output consists of connecting the input terminals to the ends of a secondary winding.
Claim 9
Independent Claim
58 words
The method of regulating the voltage from a three-phase delta-connected source to a three-phase delta-connected load circuit comprising the steps of separating each phase of the source from the other phases, maintaining substantially constant the value of voltage in each phase and recombining the regulated voltages into a three-phase delta configuration and supplying same to the load circuit.
