Abstract

A method and an arrangement for voltage measurement with a transformer configuration comprising three single pole voltage transformers having tertiary windings open-delta connected with each other. The arrangement is configured to apply a correction to measured secondary voltages on the basis of one or more parameters of the voltage transformers and/or one or more quantities in a known relation to one or more parameters of the voltage transformers, one or more parameters of a circuit connected to the secondary windings and/or one or more quantities in a known relation to one or more parameters of the circuit connected to the secondary windings, and one or more parameters of a circuit connected to the tertiary windings and/or one or more quantities in a known relation to one or more parameters of the circuit connected to the tertiary windings.
