Technical Challenges in the Commercialization of Transformers for Solar Photovoltaic Technology Applications
The presence of harmonic currents as a result of switching action of inverters, intermittent sunlight, and resonances triggered by the connection of the solar photovoltaic plant to the electrical network has spread the realization of the prospective rapid depletion of a transformer’s intended service life owing to increased service losses and temperature rise in the active components.
On the grounds of the supposed prospect of reduced transformer service lifetime under harmonic conditions, manufacturers have a growing interest in exploring transformer design procedures that enable transformers to operate reliably under harmonic conditions.
