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

Introduction Electrical power distribution networks, which include generation, transmission, and distribution, are often referred to as electrical grids. These grids have been the backbone of the world’s electricity supply since the late 19th century. Initially, the operating principles of these electrical grids were simple: generate electricity and send it to users, such as homes and … Read more

Introduction: High voltage switchboards are specialized electrical distribution equipment designed to handle higher voltage levels than standard switchboards. They are commonly used in industrial & commercial facilities, power plants, substations, and other applications where high-voltage electrical power connections are sanctioned by the local utility. Let us start with what is the relevant national and international … Read more

Background Internal Arc Faults can occur in low-voltage as well as medium-voltage switchgear panels. However, we have chosen to discuss the internal arc fault phenomenon in medium-voltage switchgear and its impact on human safety because of its severity in the latter case. What is an Internal Arc Fault? Very important to understand what this phenomenon … Read more

Introduction We have learned the fundamentals of Power Quality in our earlier article “Power Quality Basics”. We have also learned the importance of good Power Quality on Low Voltage distribution networks along with some basic calculations. Now we will go a little deeper and understand the implementation of power quality improvement methods. Power factor is … Read more

What is Power Quality? Power generated and used is with a sinusoidal wave characteristic at 50 Hz at a power factor close to unity. If it is free from other waveforms of voltage and current, then Power Quality is good. If it is mixed with other waveforms of voltage and current, then Power Quality is … Read more

Introduction A Sandwich Busway System is a means to transfer electrical power from one equipment to another equipment in a low-voltage electrical network. The other ways to transfer electrical power in an electrical network are bare or insulated solid conductors and cables. Here our topic of discussion is Sandwich Busways, its construction, and its advantages … Read more
