This asset compelled frameworks like intelligent electronic devices (IEDs) like RTUs, reclosers, PLC, V meters, video for security or gear status evaluation, metering, exchanging, volt/VAR, wave structure, occasion information, the executives and so forth. Some of the key benefits of substation automation are programmed oversight of interlocks, global and local caution and alarm, detecting fault location for distribution systems, equipment diagnostics. Digitizing Substations will offer huge expense saving, execution upgrade and safety improvements by furnishing primary equipment with current sensors and digitizing ordinary copper-based simple correspondence with secure, consistent, consistent and open standard base fibre optic correspondence.
