A new EV battery from China can travel 1,000 miles on a single charge.

A Chinese company showed off a record-breaking electric vehicle (EV) battery on Thursday. It has a volume utilization efficiency of 72 percent, an energy density of up to 255 watt-hour/kilogram (Wh/kg), the world’s highest integration level, and can go more than 1,000 kilometers on a single charge. The battery, called Qilin, after a legendary creature […]

Power System State Estimation

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

Isolation Transformer: All You Need to Know

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

Electrical Substation – Basics

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

Grounding Transformer: Solution To The Ungrounded System?

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
