The peak and effective value of harmonics When discussing the peak of harmonic currents, it's essential to first understand the fundamentals of harmonics. The effective value (RMS value) of a harmonic describes the average power of the harmonic component over one period, reflecting the equivalent extent to which the harmonic causes heating effects in the system. However, the peak of a harmonic (th...
Power quality products such as Active harmonic Filter(AHF), Static VAr Generator(SVG), Dynamic Voltage Restore(DVR) play a crucial role in ensuring the reliable efficient operation of electrical systems. Power quality issues such as votlage sags, harmonics will impact the performance and lifespan of the electrical equipment,lead to downtime and disrupt critical processe in prodution, even damage t...
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...
Introduction to our 150A AHF module A 150A Active Harmonic Filter (AHF) module is a specific type of AHF designed to handle and compensate power quality up to 150 amperes. This module is used to improve power quality by reducing harmonic distortion,compensation reactive power and unbalance in electrical systems. Here’s a detailed overview of its installations, features, working principles, a...
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...
Neutral current and Active harmonic filter Active Harmonic Filter (AHF) and Neutral Current Active Harmonic Filter (AHF) is used to improve power quality, by harmonics filtering, reactive power compensation and 3 phase balancing in power systems. Harmonics are voltage or current waveforms that are integer multiples of the fundamental frequency. They can cause various power quality issues, includin...
Introduction The best distribution system is one that will, cost-effectively and safely, supply adequate electric service to both present and future probable loads. The function of the electric power distribution system in a building or an installation site is to receive power at one or more supply points and to deliver it to the individual lamps, motors and all other electrically operated devices...
