Earthing system serves as a protective or safety measure in power systems. The process of earthing is to connect certain parts of a system with the conductive surface of the Earth.
An electrical system can often encounter issues such as current leakage, insulation failure, and short circuits. During such cases, the system as well the operators can face severe damage and harm. Current leakages in one part of a system can damage other equipment, and also pose the risk of a fatal electric shock to the operators.
An earthing system protects both people and equipment from such mishaps, by diverting the current flow from the system to beneath the Earth’s surface. Since it is such an essential safety measure, it is necessary to ensure that all power systems have a reliable, functional earthing system.
Earthing Design and Calculation
Keeping the importance of earthing systems into consideration, it is necessary that the process of designing such systems must be perfect with no room for errors.
Following data and information are required to make the necessary designs and calculations for earthing systems:
1. Site-related data which includes all drawings, schematic diagrams, and site maps.
2. System-related data which includes equipment specifications, and project design of the system and all its components.
3. Calculations for earth resistance, and ground potential rise
The designing process must take into account certain factors such as the specification of electrode rods (size, material, etc.), adherence to standards set by regulatory authorities, the requirements of the power system, and the cost of installation.
Our services in Earthing design and calculation
Howeizeh can undertake a complete earthing design for any power system. We ensure that all pieces of equipment are correctly earthed with the right sized conductor. Our team optimizes the earth nest layout to suit the site conditions and reduce costs.
We realize that the effectiveness of an earthing system can protect power systems from multiple issues, and also ensure the safety of the operators, technicians, and other personnel. That is why we put in maximum efforts and designate highly trained engineers to develop earthing designs for our clients. All calculations and designs are based on the standards set by IEEE and other regulatory bodies.
