What is the reason for high neutral line current？ Neutral current primarily arises due to two factors: three-phase unbalance and harmonic currents. Three-Phase Imbalance In a three-phase four-wire power distribution system, the ideal scenario entails an even distribution of loads across all three phases. This balance ensures that the vector sum of the three-phase currents is z...
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...
Development history of IGBTThe Insulated Gate Bipolar Transistor (IGBT) has revolutionized power electronics since its inception, marking a pivotal milestone in the development of high-efficiency energy conversion systems. Born in the late 1970s and early 1980s, the IGBT emerged as a hybrid semiconductor device that combined the advantages of Bipolar Junction Transistors (BJTs) and Metal-Oxide-Sem...
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...

In the realm of power systems, achieving top-notch power quality is a constant pursuit. One key technology that comes to the rescue is the Active Power Filter (APF). The Active Power Filter Production Line plays a crucial role in ensuring the efficient and reliable operation of power systems. Often, we only notice power quality problems when disasters strike. System malfunctions, equ...
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...
