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...
Understanding the IEEE 519–2014 Standard for Harmonics The IEEE 519-2014 standard establishes criteria for voltage and current harmonics distortion in electrical system design. It provides detailed explanations of the existing voltage and current waveforms throughout the system and sets waveform distortion goals for system designers. The standard undergoes periodic updates to stay align...
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...
