Many engineers primarily perceive earthing (or grounding) as a means of safeguarding equipment against damage or malfunction. However, prioritizing operator safety is the crucial aspect. Adequate earthing is fundamental for protection against disruptions in AC lines, be it from lightning, power-system switches, or faults in the distribution network. It also plays a pivotal role in averting radio frequency interference in transmission or computer equipment, and improper earthing can significantly degrade power quality. Establishing an effective ground network is a complex task, necessitating meticulous planning, high-quality components, and skilled installers. While it involves costs, investing in proper earthing yields long-term benefits for the facility.
