​​Overcurrent protection is critical to personal safety and protection from a number of hazardous conditions that can result from materials igniting. Short-circuits can result in arc-flashes, which can cause severe burns and sometimes prove fatal.

​​A synchronous condenser is a synchronous motor running at no load and in over-excited mode. A synchronous motor in over-excited mode behaves as a capacitor which is

Cable selection is about choosing the appropriate type of conductor and selecting a suitable size/cross-section area/ diameter of the conductor according to the application. First, there is a need to understand the significance of cable sizing and s

​​Formerly known as Underwriters Laboratories (UL), this was a non-profit organization but now it has transformed into UL LLC, a for-profit internationally accepted safety organization located in the United States and is one of the biggest & oldest

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 circuit. This operation is pe

​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.

An electrical arc is a luminous

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 of a Fault, most commonly a ...

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...

A short circuit usually occurs as a result of a fault in a power system. The fault may be a
