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...
What is difference of Active Harmonic Filter and Active Power Filter? The principle of an Active Harmonic Filter AHF is to mitigate or eliminate harmonic distortion in electrical power systems. Harmonics are unwanted currents or voltages that deviate from the fundamental frequency of the power system. These harmonics are typically generated by nonlinear loads such as variable frequency drives, com...
In the complex and ever-changing world of electrical power distribution, the accurate detection and in-depth analysis of ultra-high harmonics are matters of supreme importance. These advanced technologies specifically tailored for ultra-high harmonic detection are the linchpins in maintaining the integrity and quality of power supply within distribution networks. Among the crucial techniques is wi...
The determination of the appropriate compensation capacity is an absolutely crucial aspect in projects where the installation of reactive power compensation devices, such as capacitor banks, Static Var Generator (SVG), or Hybrid reactive power compensation devices, is imperative. For new projects: In new projects that are currently in the design stage, the required compensation capacity (kVAr) can...
The History Of Reactive Power Compensation If you are in the power industry, you must have heard of reactive power compensation. But you may not know much about it. What is reactive power compensation? Electricity from the power grid comes in two types: First, there's active power. This is the electricity that does the direct work, turning into motion, heat, chemicals, or sound to...
Introduction to Low Voltage Reactive Power Cabinet Power distribution equipment forms the backbone of modern electrical systems, efficiently managing and allocating electricity to ensure seamless power supply across various sectors. There are control gadgets that help manage how electricity flows, safety features like circuit breakers to prevent accidents, and measuring tools to check how much pow...
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 ...
