When discussing electricity usage, people often prioritize safety while overlooking a critical factor: power quality. In reality, stable, high-quality power is a cornerstone for safe and efficient industrial production and a fundamental requirement for the reliable operation of critical facilities such as hospitals, data centers, and research institutions. It also directly impacts the daily electr...

In power systems, harmonics are fundamentally caused by non-linear loads. When current flows through a load and does not maintain a linear relationship with the applied voltage, a non-sinusoidal current is produced, resulting in the generation of harmonics within the circuit. Harmonic frequencies are integer multiples of the fundamental frequency; as demonstrated by the analytical principles of th...

Harmonic pollution is one of the most prevalent power quality issues in modern industrial and commercial power distribution networks. Large-scale use of frequency converters, welding machines, UPS, EV charging piles and other nonlinear loads injects massive harmonic currents into the grid. These unwanted harmonics lead to transformer and cable overheating, frequent protection tripping, premature f...
