In industrial environments, safety is paramount. While most industries focus on advanced machinery, high-efficiency processes, and productivity, one of the most crucial safety aspects often gets overlooked—the earthing system. A proper earthing system is not just about compliance with regulations but a lifesaving investment. Faulty earthing can lead to severe accidents, equipment damage, and even loss of life. This post will explore what an earthing system is, how it works, and why it plays a critical role in industrial safety.
An earthing system (or grounding system) connects the electrical equipment and installations to the ground through a low-resistance path. The goal is to provide a safe route for electrical fault currents to flow into the earth, preventing the buildup of dangerous voltages. In other words, it keeps the exposed metal parts of machinery and devices from carrying unsafe voltages that could harm workers.
In industrial environments, employees often work with heavy machinery and electrical panels. If the equipment is not properly grounded, accidental leakage currents can make the metal parts live, posing a severe shock hazard. Proper earthing ensures these currents are redirected safely into the ground, preventing injury and fatalities.
Short circuits and ground faults are common in industries, especially in harsh environments like chemical plants, power stations, and manufacturing units. When fault currents don’t have a proper path to dissipate, they generate heat, potentially igniting fires. An efficient earthing system protects both workers and the facility by safely carrying fault currents into the ground.
Electrical equipment such as transformers, control panels, MCCBs, and motors can be easily damaged by voltage surges or lightning strikes. These sudden spikes cause insulation breakdowns, resulting in expensive repairs and operational downtime. Earthing systems play a key role in mitigating these risks, prolonging the life of equipment, and ensuring smooth industrial operations.
Industries are required to comply with safety standards, such as IS 3043 (Indian Standard for Earthing) or IEC 60364. Non-compliance can result in fines, shutdowns, or even accidents. Proper earthing ensures compliance with national and international safety standards during audits, inspections, and certifications.
Before installation, conduct a professional earthing audit to determine the soil resistance, fault levels, and current-carrying capacity. This ensures the design will meet the site’s specific needs.
Using high-quality copper rods, plates, and earthing wires ensures better conductivity and durability. Corrosion-resistant materials help avoid failures in the long run.
Routine inspection and testing of the earthing system is crucial. Over time, connections may loosen, or electrodes may corrode. Regular testing ensures the system continues to perform effectively.
Adding SPDs along with earthing provides extra protection against lightning and surges, particularly for sensitive electronic equipment such as control panels, PLCs, and sensors.
In a chemical manufacturing unit in Rajasthan, an unexpected lightning strike hit the facility. Thanks to the professional earthing system installed with chemical rods and SPDs, the fault current was immediately diverted into the ground. Not only were the control panels and equipment spared from damage, but no injuries were reported. Without a reliable earthing system, the plant could have suffered severe equipment failure, a hazardous chemical spill, and potential loss of life.
