VERFAHREN ZUR POLARITAETSERKENNUNG VON ELEKTRONISCHEN BAUTEILEN UND ANORDNUNG ZUR DURCHFUEHRUNG DES VERFAHRENS.

摘要

AC voltage is applied to the connections of the component (1) and the currents flowing over tha outer covering (2) to a sensor (6) indicate the polarity of the component. The relative magnitudes of the currents decide the polarity. The ac voltages are applied with different phases to the connections to the component and the phase of the current flowing over the outer covering to the sensor is taken as a measure of polarity. The frequency and amplitude of the two ac voltages are the same and the phase shift is 180 degrees.
