Fonction

TO MAINTAIN A CONSTANT CURRENT THROUGH A SERIES STRING OF ELECTRIC LIGHTS

Technique

EARLY EXAMPLE OF AN AUTOMATIC AC CURRENT REGULATING DEVICE. IT WAS THE PRACTICE TO SHORT OR CUT THE CURRENT THROUGH A LAMP SOCKET IF THE LAMP WERE REMOVED, TO KEEP THE STRING OPERATIONAL. THIS DEVICE MAINTAINED A CONSTANT CURRENT THROUGH THE REMAINING LAMPS. SUBSTANTIALLY CONSTANT VOLTAGE IS APPLIED TO THE PRIMARY WINDING CONSTANT CURRENT WILL FLOW IN THE SECONDARY WINDING REGARDLESS OF THE IMPEDANCE APPLIED ACROSS IT. ABILITY TO REGULATE SECONDARY CURRENT IS INHERENT IN DESIGN: SECONDARY COIL FREE TO MOVE TO & APART FROM FIXED COIL (REF.2)
