Abstract
The invention concerns an electrical installation providing an apparatus, a three-phase inverter and a control device, the inverter being adapted for generating a three-phase current presenting a first frequency for operating the apparatus and an undesired frequency component presenting a second frequency. The control device is adapted for measuring a parameter of each phase of the current, the measured parameters forming a measurement vector, and for calculating a Clarke transform, providing a first vector represented in a first basis of a two-dimensional vector space, of the measurement vector. The control device is adapted for generating a representation of the first vector in a second basis of the vector space, the second basis rotating at the second frequency with respect to the first basis.
