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 ...
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 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...

What is the active power compensator? Active Power Compensator (APC) is an advanced power electronic device used to manage and optimize the flow of active power in electrical power systems. It helps to enhance power quality, improve voltage stability, and increase the overall efficiency of the power distribution network. APCs are particularly useful in applications where there are significant fluc...
kVAr and Amps in power quality Reactive Power (kVAR) Reactive power, measured in kilovolt-amperes reactive (kVAR), is the component of alternating current (AC) power that does not perform any actual work but is necessary for maintaining the voltage levels required for the active (real) power to do useful work. It is associated with the energy storage in inductive and capacitive elements of the pow...
Reasons of Neutral Current The neutral current is the current flowing through the neutral conductor in a multi-phase electrical system. In a perfectly balanced system, the sum of the currents in all phases should theoretically cancel each other out, resulting in zero neutral current. However, in practice, various factors cause current to flow in the neutral conductor. Reasons for Neutral Cur...
