A circuit breaker is a power system protection device that can make or break a circuit

A circuit breaker operates under fault conditions and isolates the faulty part of the circuit from the rest of it by breaking the c

​Arc Flash incident is one of the most dangerous hazards faced by electricians all over the world. According to statistics, 5 to 10 arc flash explosions occur in electric equipment every day in the United States.

In power systems, it is a common occurrence that there are unbalanced voltages and currents on the distribution side of the grid. But these voltages and currents might be unbalanced anywhere through the grid in the case...

With the expansion of electric power in today's world, electrical power systems are exposed to many critical conditions like overvoltages and voltage surges due to lightning strikes or abrupt switching conditions. The main concern is the overvoltage co...

The short circuit is essentially an abnormal condition within a power system in which a heavy amount of current flows through the circuit.

A short circuit usually occurs as a result of a fault in a powe

Load flow, also known as Power Flow Analysis, is an essential method to examine the problems occurring in the power systems network or grid.

Load flow Analysis is performed to determine the state of the equipment p

We often hear the term 'Power Factor' in electrical power systems. But, how do we define 'Power Factor' in an electrical world?

In this article, we will be discussing power factor in detail including its significa...
