process and apparatus for the measurement of the resistance of a coil and the resistance of contact and / or welding

摘要

this found it has as its object a method and related equipment to carry out the measure of the resistance of a coil.and the resistance of contact and / or welding windings in series, not closed to closed ring and ring, which uses a power generator and differential amplifiers.for the measure of the resistance of the coil, and differential amplifiers, for measuring the resistance of contact and / or welding, among them operationally connected.
