Abstract

The method involves calculating a secondary voltage drop between ends of a secondary winding (54) based on characteristics and a load factor of an electric transformer (18), and a power factor of a load connected to the winding in an output of the transformer. A module of a primary voltage is calculated based on a measured secondary voltage, the calculated voltage drop and a transformation ratio of vacuum. A phase difference of a primary voltage relative to a primary current measured by a phase shift of the secondary voltage measured relative to the measured primary current, is calculated. Independent claims are also included for the following: (1) a system for determining a primary voltage of an electric transformer (2) a transformer station.
