Development of an embedded instrument for the quality analysis of electricity in an industrial network

The job aims at the production of an embedded system for the quality analysis of electricity in an industrial network. The consultant will have to continue a work in progress which has recently get a first prototype; he will develop both software and hardware, to attain a stage of pre-production. It's mandatory to keep the current hardware architecture, "Arduino Due". It is first necessary to develop a new revision of the printed circuit board that allows to overcome some problems typical of this first batch, such as the exclusion of the negative half-wave or various issues with stability at application of heavy loads.\r\nPlease add the word elephant in your candidature, otherwise it will be automatically cancelled. Subsequently, software will be written (and shared), so that it permits the identification of defects typical of industrial distribution as sag, swell, flicker, three-phase unbalance, frequency variations, and analysis of harmonic distortions. The ideal applicant has a good experience in terms of prototyping circuit boards and excellent programming Arduino Due skills. Preference factor is confidence with features of industrial distribution.
