In an electrical systems, surge protection devices (SPDs) are usually installed in tap-off configuration (in parallel) between the live conductors and the earth. The operating principle of SPD can be… Read more
The subject of this technical article are harmonic filters and their design. Filtering measures are recommended and may be required for electrical systems with too high harmonic levels. Filter circuits… Read more
The pumped storage power plants (PSPP) are one of the commercially proven methods available for grid-scale energy storage. Building additional PSPPs particularly in the areas with high installed capacities of… Read more
Reactive energy compensation is an essential process in improving energy efficiency. It reduces the power consumption and thus its cost, enables optimum use of installations by preventing them being oversized,… Read more
Most practical power system problems are solved by using steady state analytical methods. These methods make the assumption that circuit parameters are linear, bilateral, and constant for constant frequency circuit… Read more
It’s extremely important to work on selective coordination of circuit breakers in the design phase of a system. After switchboards, distribution panels, MCCs, lighting switchboards, etc. are installed, there typically… Read more
Due to the critical nature of the care being provided at healthcare facilities and their increasing dependence on electrical equipment for preservation of life, they have special requirements for the… Read more
