Method and apparatus for measuring the resistance of a winding, and the contact and/or welding resistance of windings in series, whether or not closed in a ring

摘要

The purpose of the present invention is a method and the corresponding apparatus for performing the measurement of the resistance of a winding, and of the contact and/or welding resistance of windings in series, whether or not closed in a ring, which makes use of a current generator and differential amplifiers for the measurement of the resistance of the winding, and differential amplifiers for measuring the contact and/or welding resistance, operatively connected to each other.
