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

Introduction Our discussion here will be limited to Medium Voltage Switchgear up to 33kV. Before we understand solid insulation switchgear technology, we will first go into the history of medium voltage switchgear solutions. If we talk of evolution of medium voltage solution, then we can broadly categorize them under two sections as given below: On … Read more

Background (Courtesy: Tricolite Electrical Industries Ltd) The validity period of type tests for switchboards are many a times debatable if it is older than five years. I am sure as an engineer you have also faced this challenge during some of your interaction with your clients. We all that power equipment undergo developmental stage before … Read more

Background This seems to be a very odd topic of discussion as we never thought of Energy Efficiency for LV Switchboards. I have presented this in the 2nd Edition of EEETech organised by CII at IHC Delhi, which was a Technical Conference and exposition on Energy Efficiency, Environment and Technology. The theme of the exposition … Read more
