In power systems, transformers, as core equipment, undertake the crucial task of voltage conversion. However, due to manufacturing defects, environmental factors, and long-term operational wear, various faults frequently occur—oil leakage, abnormal oil levels, damage to the oil conservator bladder, deformation of the cooling system, and abnormal internal noises are common problems. These issues no...

In power supply systems, power factor is a crucial indicator, directly reflecting the efficiency of electrical equipment. A higher power factor means that electrical equipment is fully utilized and operates more efficiently; conversely, a lower power factor means lower utilization, like a car with a powerful engine that fails to deliver its full potential due to various reasons, wasting energy. Po...

Analysis of the reasons for the decrease in power factor on the power supply side after the AHF only performs harmonic filtering: I. Increased total apparent power naturally leads to a decrease in the overall power factor. Power factor λ = P/S. Active power P is determined only by the fundamental active power; harmonics do not contribute. After filtering, the fundamental reactive power remains unc...

Many charging station operators have a question: when charging piles are charging normally, the power factor is perfectly within the standard range, and there are no problems even without capacitor banks or SVG. However, when the station is newly built, there is little traffic, or there is no one charging at night, the power factor inexplicably exceeds the standard, resulting in power factor adjus...

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...

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...

In power quality management, different voltage levels often require different harmonic mitigation strategies. In low-voltage systems, Active Harmonic Filters (AHFs) are widely used because they offer flexible and precise harmonic compensation. However, when it comes to medium- and high-voltage power systems, passive Filter Capacitor (FC) systems remain a more common and practical solution. So, why...
