Introduction To Capacitors And Reactors Reactance includes inductive reactance and capacitive reactance, and reactor includes inductive reactance (inductor) and capacitive reactance (capacitor). Inductance has the function of blocking AC and blocking DC, that is, in the AC circuit, the characteristics of inductive reactance are used to pass low-frequency DC and block high-frequency AC. The capacit...
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 is harmonic and how to manage it? Harmonics denote electrical quantities that possess frequencies which are integer multiples of the fundamental wave present in the current. This concept typically involves the Fourier series decomposition of periodic, non-sinusoidal electrical quantities. In this context, any electrical quantity with a frequency exceeding that of the fundamental wave, derived...
What are the power quality problems of broadband oscillation? Broadband oscillations in power systems refer to low-frequency oscillations that occur over a wide range of frequencies. These oscillations can have a significant impact on system stability and can lead to voltage instability, power quality issues, and even blackouts if not properly managed. Here are some of the characteristics of broad...
In today's rapidly advancing world, the reliability and quality of power have become more critical than ever. The interconnected systems and sensitive electronic devices of the modern digital economy require an almost perfect power supply. However, power quality (PQ) issues such as voltage sags, harmonics, and transients remain prevalent, posing significant challenges to utilities and end-users al...
