Transformer having reduced differential impedances between secondary portions

Claim 1

A DISTRIBUTION TRANSFORMER COMPRISING A MAGNETIC CORE HAVING A WINDING RECEIVING CORE LEG, A PRIMARY WINDING COIL SURROUNDING SAID CORE LEG AND HAVING CONNECTION MEANS FOR CONNECTING SAID PRIMARY COIL TO POWER SUPPLY MEANS, FIRST AND SECOND SECONDARY WINDING COILS SURROUNDING SAID CORE LEG IN INDUCTIVE CONCENTRIC RELATION WITH SAID PRIMARY WINDING COIL AND DISPOSED RESPECTIVELY ON RADIALLY INNER AND OUTER SIDES THEREOF, EACH OF SAID SECONDARY COILS HAVING SUBSTANTIALLY AN EQUAL NUMBER OF CONDUCTOR TURNS SO THE SUBSTANTIALLY EQUAL VOLTAGES ARE INDUCED THEREIN WHEN SAID PRIMARY WINDING COIL IS CONNECTED TO SAID SUPPLY MEANS, AND MEANS INCLUDING CONNECTION MEANS ON EACH OF SAID SECONDARY COILS FOR SELECTIVELY CONNECTING SAID SECONDARY COILS IN SERIES CIRCUIT RELATION WITH EACH OTHER TO PROVIDE A VOLTAGE ACROSS SAID SECONDARY COILS SUBSTANTIALLY EQUAL TO TWICE THE VOLTAGE INDUCED IN ONE OF SAID SECONDARY COILS AND IN PARALLEL CIRCUIT RELATION WITH EACH OTHER TO PROVIDE A VOLTAGE ACROSS SAID SECONDARY COILS SUBSTANTIALLY EQUAL TO THE VOLTAGE INDUCED IN ONE OF SAID SECONDARY COILS, SAID FIRST AND SECOND SECONDARY COILS HAVING FIRST AND SECOND PREDETERMINED RESISTANCE PER UNIT LENGTH OF TURN VALUES, RESPECTIVELY, SAID VALUES BEING IN A PREDETERMINED RATIO IN WHICH SAID FIRST VALUE IS PREDETERMINATELY GREATER THAN SAID SECOND VALUE TO REDUCE THE DIFFERENTIAL BETWEEN THE IMPEDANCE VALUES OF SAID SECONDARY COILS.
