摘要
The present invention discloses a method for error compensation in metering devices using Rogowski coils in a circuit breaker, wherein said method comprising: storing, by using at least one barcode, values corresponding to amplitude and phase angle of said Rogowski coils for different phases, to enable calibration of said rogowski coil; scanning, by using scanner means, said barcode and/or said said Rogowski coils for each phase to obtain calibration data, during assembly of said circuit breaker; communicating, by a communication means, said calibration data from said scanner means to an electronic system, wherein said electronic system is adapted to communicate said calibration data to said metering devices; storing, by said metering devices, said calibration data, wherein during normal operation of said circuit breaker said metering devices adapted to enable, by means of a metering module, accurate metering using said stored calibration data.
