Abstract

The present invention relates to an apparatus for calibrating a power measuring system for power transformers. The general inventive concept involves the two reference measuring systems that are known from the prior art for the calibration of a current transformer, a voltage transformer and an evaluation device being integrated in a shared apparatus, according to the invention, for calibrating a power measuring system for power transformers, which apparatus is furthermore arranged on a container such that the apparatus can be moved by means of a trailer that holds the container for the purpose of in-situ calibration of the power measuring system of power transformers.
