System for monitoring a transformer

Abstract

This invention concerns a system for monitoring a transformer which comprises multiple terminals. The system includes multiple measuring devices and a transformer monitoring device. Each measuring device is arranged adjacently to a terminal of the transformer. Each measuring device includes a housing, a processing unit, a terminal to connect the processing unit to a sensing means to sense an electrical magnitude at the terminal of the transformer, and a data transmission terminal to transmit data between the processing unit and the transformer monitoring device. The transformer monitoring device, which is connected to the multiple measuring devices, is designed to determine, from a combination of the data from the multiple measuring devices, a present state of the transformer.
