Protective Relay Wiring Diagram

It reveals the components of the circuit as simplified shapes and also the power and signal connections in between the tools. Diagrams will show how multiple relays one relay or another or just one relay can control your device. Dc schematics often referred to as elementary wiring diagrams are the particular schematics that depict the dc system and usually show the protection and control functions of the equipment in the substation.
