What is Grounding?
<p>Grounding is an essential electrical safety measure to ensure the safe operation of devices and electrical systems. Grounding involves securely connecting metal components in an electrical circuit (such as devices, electrical panels, etc.) to the ground. This helps to ensure the safety of both individuals and devices in the event of potential issues like leakage current or faults in the electrical circuit.</p> <p><strong>How Grounding is Done:</strong></p> <ol> <li> <p><strong>Selection of Grounding Electrode:</strong> The grounding electrode is typically a metal rod or plate. The choice of the electrode is determined based on soil conditions and local regulations. Copper or galvanized steel is commonly used.</p> </li> <li> <p><strong>Placement of Grounding Electrode:</strong> The grounding electrode is placed near the device or electrical panel. It should have good contact with the soil. A hole is dug for the electrode, and it is placed inside. The hole is then filled, and the top of the electrode is brought to ground level.</p> </li> <li> <p><strong>Connection of Grounding Cable:</strong> The grounding electrode is connected appropriately to the metal part of the device or panel using a suitable grounding cable, often made of copper or aluminum.</p> </li> <li> <p><strong>Grounding System Check:</strong> The grounding system should be regularly checked. These checks include measuring the grounding resistance. The grounding resistance measures the electrical resistance between the grounding electrode and the soil and should typically be below a certain value.</p> </li> <li> <p><strong>Grounding Connections:</strong> Electrical panels, devices, and other metal components should be properly connected to the grounding system. These connections establish a loop in the grounding system, effectively grounding the metal parts of devices.</p> </li> </ol> <p>Grounding is considered a fundamental electrical safety standard, providing a crucial measure for ensuring the safety of users and devices in electrical systems.</p>
