Optical measurements of vibration of Medium Voltage transformer

In questo lavoro si presentano i primi risultati di misure di vibrazione della cassadi un trasformatore MT eseguite con un sistema ottico assemblato da RSE e conconnessione wireless all’unità di controllo.

This paper describes an assembled optical prototype for measurements of vibration of a distributing transformers tank. It consists of optical MEMS accelerometers, .an acquisition unit wireless connected to a remote PC. A SW interface was developed to simultaneously control configuration settings of input channels, the display on the PC screen of acquired data and their storage. Preliminary tests were performed on a conventional type distribution transformer (30kVA); results of comparative analysis with standard piezoelectric accelerometers used as references confirm the feasibility of the proposed approach.
