BS PD IEC TS 62738:2018 sets out general guidelines and recommendations for the design andinstallation of ground-mounted photovoltaic (PV) power plants. A PV power plant is definedwithin this document as a grid-connected, ground-mounted system comprising multiple PVarrays and interconnected directly to a utility's medium voltage or high voltage grid. Additionalcriteria is that PV power plants are restricted from access by non-qualified persons and arecontinuously monitored for safety and protection, either by on-site personnel or by activeremote monitoring. Technical areas addressed are those that largely distinguish PV powerplants from smaller, more conventional installations, including ground mounted arrayconfigurations, cable routing methods, cable selection, overcurrent protection strategies,equipotential bonding over large geographical areas, and equipment considerations.
