Abstract
A deregulated energy market needs demonstrably correct energy measurements for correct billing. Voltage transformers may be prone to drift implying a need for verification of their errors. A method to do this on-site using previous calibrations and comparative measurements has been developed and its uncertainty has been estimated.
