Power system state estimation is still a new branch of electrical power engineering, aged approximately three decades. Various research has been happening on this topic, but if I have to take a textbook to get a sound understanding, I would definitely take the book written by Dr. Ali Abur. It is concise and written in […]
The smart grid is a new technology that changes the way electricity is produced, delivered, and consumed. It’s the next step in the evolution of the electricity grid. The smart grid is a combination of the traditional grid and information technology. The conventional grid transfers electricity from power plants to consumers, and it’s based on
A blockchain is an encrypted, decentralized public ledger that keeps track of transactions and data transfer. It’s an innovative, new technology that is poised to disrupt many industries and has the potential to change the way we interact with one another. What is blockchain technology? BlockChain is an innovative type of distributed ledger that was

Sometimes we see small isolation transformers in electronic devices and might be wondering what the use of this mini transformer is. Single-phase power wiring uses a hot wire, a neutral wire, and a ground wire. If multiple devices share a single power line, those devices can have different ground potentials. This creates a problem known
An electrical substation is one of the most important building blocks of the power system. They are used to transform AC voltages from one level to another voltage level. We may not notice, but after generation from an electrical power plant, electrical power travels a great distance and is transformed into different voltage levels throughout
Introduction: What does one do when the neutral point is not available? As the ungrounded system problems became more apparent to industry, they recognized that ground their delta-connected systems was to their advantage. Some took the approach of purposely grounding one phase. Neutral points are an excellent way to ground an ungrounded delta system because

What is Current Transformer? A current transformer is an instrument transformer also known as CT, used to step down the line current of an electrical circuit so that it can be used in the revenue meters and in the protection relay. As we know typically the line currents are high enough. So to safely use
Introduction: Renewable energy is one of the most promising areas of alternative energy. It is now cheaper to generate electricity from solar and wind power than from fossil fuels. As the cost of renewable energy continues to come down, more and more companies are starting to use it as a primary source of energy instead
