Abstract (en)
[origin: WO2019174869A1] The invention relates to a method, carried out by at least one device, comprising: determining a correction factor for at least one first voltage transducer arranged in an electrical grid, the correction factor being indicative of a correction for obtaining correct measurement values measured by the at least one first voltage transducer, the correction factor of at least one first voltage transducer being determined at least partially on the basis of a first measured voltage of the at least one first voltage transducer and a second measured voltage of the at least one first voltage transducer, the second voltage of the at least one first voltage transducer being determined at least partially on the basis of a previously known transfer function of at least one second voltage transducer and the first voltage of the at least one first voltage transducer being determined without consideration of the previously known transfer function of at least one second voltage transducer; determining a calibration factor for the at least one first voltage transducer at least partially on the basis of the determined correction factor; and outputting or triggering the output of the determined calibration factor. The invention further relates to a correspondingly designed device and to a system.
