Instrumentation Earthing in Industrial Automation Systems
In industrial automation, earthing provides a safe, low-resistance path for electrical fault currents. It protects both equipment and personnel by diverting excessive current directly into the ground. Proper earthing is fundamental to PLC, DCS, and control system reliability, ensuring stable operation even under fault conditions.
