Drysdale's Alternating and Continuous Current Potentiometer
Dr. C.V. Drysdale's Alternating and Continuous Current Potentiometer.
This instrument dates back to 1909 and comprises the standard Tinsley DC potentiometer of the time, with a phase shifter, Weston dynamometer voltmeter, selection and change-over switches and terminal panels for connection of galvanometers, DC and AC measuring and supply voltages. Measures voltage as magnitude and phase from reference voltage.
Monash University, Department of Electrical and Computer Systems Engineering of Australia describes this machine as “Possibly the most technically significant or the measuring instruments”.
