Earthing is an important part of electrical distribution lines. Installation of a protective grounding on the power line structure creates a safe work zone. It neutralises leakages or short-circuit current and offers a simple and easy path for the current to the earth with zero damage potential. Importance of Earthing ...
The fundamental role of any substation earthing is to dissipate the short circuit current into the earth without drying out the area and to limit the potential gradient throughout the substation to maintain the step and touch voltages within safe values. There are two features considered during the design of ...
In an electrical substation, Lightning Protection System is important for the smooth operation of electrical networks during lighting strikes. Lightning strikes can cause severe damages due to the surge of extra voltage during a strike that is injected into a transformer. As a result, a strike and switching can cause ...
Follow us on LinkedIn for the latest updates The importance of Bonding, Grounding and Earthing in electrical systems cannot be overstated. In a factory, in order for the equipment to function properly, the grounded circuits need an effective return path from the equipment to the power source. In any kind ...
Standards Used for Earthing Systems Definitions Over the past century, Electrical Safety Standards have evolved into highly developed systems that cover all the major aspects for a safe installation, including Earthing Systems. In Low-voltage (LV) Electrical Installations, the reference standard IEC 60364 is used for the measures to be implemented ...
Type A & Type B Earthing as per IS/IEC 62305-3:2011 IEC 62305 Part 3 defines two types of arrangements for Earth Electrodes used for structural protection, Type A and Type B. Both of these arrangements form an integral part of the Earth Termination system for the structure, the importance which ...
Myth 1: Chemical Filled Electrodes are long lasting and maintenance free Corrosion resistance is one of the primary requirements from an effective electrode – it will determine the working life of the entire earthing system. Detecting failed earth electrodes is not easy since they are buried far underground. Two long ...
