ABSTRACT:
A method and system for the measurement of energy in an alternating-current motor drive containing a frequency converter or an equivalent stepless rotational speed regulator provided with semiconductor switches. In this regulator, the power taken by the motor drive from the mains is determined, and based on the power taken by the motor drive from the mains, the energy taken from the supply mains, especially the accumulated energy consumption after a given instant is determined.
