What type of signal does a Guard (piloting relay) provide?

A Guard, or piloting relay, provides a continuous pilot signal in a transmission system, ensuring the consistent operation of equipment and safety protocols. This signal acts as an ongoing assurance that the particular system's conditions are met, allowing for the proper management of assets within the electrical grid.

Continuous pilot signals are essential in signaling the status of the grid or equipment, indicating that everything operates smoothly and efficiently. By maintaining this steady signal, the system is able to mitigate the risk of unexpected equipment failures or errors during critical operations. The nature of the continuous pilot signal helps operators to monitor and control various aspects of the transmission process while fostering a safer environment for the electrical infrastructure.
