Abstract
"An electrical voltage variation detector" powered by the voltage whose variations are to be detected, either directly if it is a direct voltage, or previously rectified if it is alternating, and constituted by a Wheatstone bridge formed by three ohmic resistances and a fourth resistance constituted by an ohmic resistance of high positive or negative temperature coefficient, such as platinum, nickel, etc., or coal or carbon filament lamps, provided that the other three are of nicron, constantan, nickel or similar.
