The quality of electricity directly determines the energy-saving ratio of a company's power consumption system, as high-quality electricity can prevent significant energy waste. So, what is electricity quality, and what factors affect it? What is power quality? Power quality generally refers to the quality of alternating current (AC). That is, the AC power supplied by the power industry to busines...

In industrial production, enterprises often face two major challenges: fluctuating production efficiency and persistently high electricity costs. Most of the time, managers attribute these problems to aging equipment and improper operation by personnel, overlooking a hidden killer lurking in the power system—harmonics. As "electrical pollution" in the power system, harmonics not only directly incr...

Are your factory's electricity bills skyrocketing? Are precision equipment breaking down unexpectedly? Are your transformers frequently overheating? Are you being fined by the power company for failing to meet power factor standards? These troublesome problems often point to the same root cause— power quality . In the field of power quality management, two star devices are frequently mentioned: SV...

Many new energy vehicle manufacturing plants and charging stations encounter issues such as excessive power factor at night and inexplicable fines for over-compensation. Everyone knows that resolving capacitive overcompensation requires installing reactors to absorb excess capacitive reactive power. However, the vast majority of electricians on site fell into the same trap: they directly used the ...

In power distribution systems, capacitor banks compensate for the reactive power generated by inductive loads using parallel-connected low-voltage power capacitors; this improves the power factor, reduces line losses, and avoids utility company penalties. However, a common misconception exists: the belief that the more capacitors are engaged—and the higher the resulting power factor—the better. In...

1.Why is reactive power compensation necessary? Reactive power is by no means useless power. In AC power supply systems, inductors and capacitors serve as essential loads. Ferromagnetic loads—such as electric motors and transformers—cannot function without inductive reactive power for excitation; meanwhile, long-distance transmission lines possess inherent capacitive characteristics, effectively a...

In modern power systems, reactive power compensation is widely used to improve power factor, reduce line losses, and increase the efficiency of electrical equipment. However, when the power source is a diesel generator, gas generator, or other synchronous generator, pursuing an extremely high power factor is not always a good idea. At first glance, a power factor close to 1.00 seems ideal. But for...

Variable Frequency Drives (VFDs) have become essential in modern industrial systems. They provide accurate motor speed control, reduce mechanical stress, and can significantly improve energy efficiency. However, there is another side of VFD technology that is often underestimated: harmonic distortion. In low-voltage distribution systems, a large number of VFDs can become an important source of har...

In low-voltage power factor correction systems, detuned reactors are widely used together with capacitor banks to prevent harmonic amplification and protect capacitors. Among the most common configurations, 7% and 14% detuned reactors serve different purposes and require different capacitor specifications. A 7% detuned reactor typically creates a tuning frequency of approximately 189 Hz in a 50 Hz...

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...
