13.2kV medium voltage switchgear single line diagram with four incoming cells for BESS, solar, diesel generation, and one outgoing cell to main transformer on a 600A common busbar. Each cell integrates a 13.2kV/630A vacuum circuit breaker, IEC 61850-compliant protection relay with differential, overcurrent, undervoltage, and overvoltage functions, plus current and potential transformers for metering. The switchgear connects to a remote control and monitoring panel via SCADA/EMS gateway supporting IEC 61850, Modbus TCP, and DNP3 protocols. This architecture demonstrates best practice for hybrid renewable and backup generation integration with centralized protection and energy metering.
