Surge Arrester Considerations in Utility Scale Photovoltaic Systems

Development of photovoltaic generation systems ranging from 2 MW to 30 MW has increased significantly. Design of such larger PV systems that interconnect to medium voltage distribution lines can include a variety of strategies for surge arrester placement. Since interconnection design is a repetitive process, the system designer often includes template designs to avoid system studies from project to project. This presentation explains how proper evaluation of the system and design can reduce the quantity of distribution components, reduce the equipment insulation levels required and ultimately lower system costs.
