What is the power factor correction? Power factor correction (PFC) is a technique used to improve the power factor of an electrical system. Power factor is a measure of how effectively electrical power is being used. It is defined as the ratio of real power (measured in kilowatts, kW) used to perform work to the apparent power (measured in kilovolt-amperes, kVA) drawn from the power source. Power ...
In an electrical power system, harmonics basically means the multiples of the current or voltage at the fundamental voltage frequency. Whenever you look at a waveform and it's not the usual sinewave shape you expect, that means there are harmonics involved. What causes Harmonics? Well, AC signals can be divided into linear and nonlinear. The nonlinear systems draw power in short, sudden pul...
what are the effects of harmonics on electrical systems In the intricate realm of electrical engineering, harmonics emerge as a subtle yet influential phenomenon that can significantly impact the efficiency, reliability, and safety of electrical systems. These unwanted frequencies, riding alongside the fundamental power waveform, can wreak havoc on various components and overall system perf...
How SVG compensation for leading reactive power? What kind of load is prone to generating leading power reactive power? Leading power factor conditions typically occur when a system has capacitive loads or a surplus of capacitive reactance over inductive reactance. Capacitive loads store energy in an electric field, unlike inductive loads that store energy in a magnetic field. When these lo...
Neutral Current and Single-Phase Loads Neutral current is an essential aspect to consider in electrical systems, especially when dealing with single-phase loads in a three-phase system. The presence of single-phase loads can lead to various issues related to N line current, impacting the overall power quality and safety of the system. Understanding N line Current in Systems with Single-Phase Loads...
