Switchboard Engineering Simplified
Introduction Environmental impact is a topic that often gets overlooked during the design phase of a switchboard. While designers usually consider ambient temperature as a primary environmental parameter, several other critical conditions—such as humidity, salinity, and pollution levels—play an equally important role in ensuring the long-term reliability of MV switchboards. Why do these conditions matter? … Read more
Introduction To understand the bus bar as a critical element of switchboard assembly, we can draw an analogy with the human body. Just as healthy veins are vital for circulating blood throughout the body to ensure proper functioning, a properly designed bus bar system is essential for distributing electrical power safely and reliably within a … Read more
Introduction Type testing of medium-voltage (MV) switchboards in NABL-accredited laboratories is a mandatory requirement for compliance with IEC 62271-200. These tests verify critical aspects such as dielectric strength, temperature rise, short-time current withstand, and internal arc classification. However, switchboards are usually offered in multiple variants within the same product family—differing in current ratings, fault levels, … Read more
Introduction Every moment in life, we are selling something—sometimes knowingly, sometimes unknowingly. Surprised? You might say, “But I’m not a salesman.” Think again. Imagine the moment just before your annual appraisal when you’re convincing your manager to recommend a higher raise. What are you really doing? You’re selling—selling yourself through your achievements. Selling, at its … Read more
Introduction In a previous article, we discussed the various types of faults encountered in an electrical distribution network. In this article, we focus on one of the most severe types — the short-circuit fault. For the smooth and reliable operation of any electrical distribution system, it is essential to provide adequate protection against abnormal conditions. … Read more
Introduction In today’s heavily mechanised and digitised world, electricity forms the foundation of modern living. From homes and offices to large-scale industries and infrastructure like highways, railways, airports, and ports—every function relies on a stable, uninterrupted power supply. At the heart of this dependency lies the electrical distribution system, which ensures the delivery of power … Read more
Maintaining calm in a fast-paced world filled with daily pressures can feel like an elusive goal. Whether it’s a stressful work environment, personal challenges, or unexpected setbacks, knowing how to stay composed is a powerful skill that benefits both mental and physical health. Keeping calm doesn’t mean suppressing emotions or avoiding challenges; it means managing … Read more
Introduction In another article, “Sheet Metal Enclosures for Electrical Switchboards: A Cornerstone of Electrical Safety and Reliability” we discussed the importance of sheet metal enclosures for electrical switchgear assemblies. We have also discussed the type of metal enclosures. We all know that all metals are prone to environmental degradation, and painting is one of the … Read more
An Introduction Let us first understand what Empathy is. How is it connected with leadership? And what is the importance of this trait in a leader? In today’s time, when the pace of life is so high, it is very difficult to keep oneself calm and motivated all the time. The majority of working adults … Read more
Introdcuction In the world of electrical systems, sheet metal enclosures play a vital role in ensuring the safety, reliability, and efficiency of electrical switchboards. These are not just protective enclosures, rather they do more than that. They are engineered structures designed to withstand environmental challenges, prevent electrical hazards, and provide seamless integration of switchgear & … Read more
