Characteristics of reactive power compensation capacitor
Characteristics of reactive power compensation capacitor: ① Reactive power compensation capacitor is a capacitive reactive power supply source that operates for a long time under power frequency AC voltage. The reactive power compensation capacitor's own active power loss is small, accounting for about 0.3~0.5 of the ordinary reactive capacity. The power capacitor device is simple, easy to use, maintenance workload is small, a less investment. ④ Due to the structural characteristics, high ambient temperature and operating voltage will affect its applicable performance and life, and even form an accident. ⑤ The reactive power of the capacitor is proportional to the square of the voltage. When the system voltage decreases and more reactive power compensation is required, the reactive power of the power capacitor is reduced at this time, showing the lack of performance. Power capacitor is the power system reactive power compensation of the wrist, the operation of the parallel capacitor capacitive current offset rational current, so that the transmission components such as transformers, lines in the reactive power response is reduced, therefore, not only reduces the reactive power flow caused by the active loss, but also reduces the voltage loss, improve the power factor. So the use of parallel capacitors to stop the reactive power compensation at all levels of the power grid is the most common application of the power system.

Benefits of Reasonable Selection and Application of Reactive Power Compensation Capacitors
The benefits of reasonable selection and application of reactive power compensation capacitors: ① The choice of capacitor rated capacity should pay attention to matching the transformer capacity. It is difficult to obtain a reasonable supplementary effect if the rated capacity of the capacitor is too large or too small. ② Avoid frequent switching of the capacitor switch. Frequent switching of capacitor switches will produce extremely high peak current, which will do great harm to the normal operation of switch electricity, often resulting in the sudden onset of shortened service life or damage problems of switch electricity.

Measures for reactive power compensation of electricity-consuming enterprises
Reactive power compensation method for electricity enterprises: electricity enterprises generally use parallel capacitors to stop reactive power compensation, in order to improve the power factor, reduce the current of the power supply line and reduce the line loss, but in practice, the compensation effect of different compensation methods is different. ① The effect of high-voltage capacitor reactive power compensation on the progress of the total circuit power factor is significant, but for the enterprise's power saving effect, it is not as good as the direct compensation of low-voltage power grid and electrical equipment. ② Low-voltage capacitor centralized reactive power compensation

Overview of Multi-function Harmonic Maintainer
Overview of multi-function harmonic maintainer: multi-function harmonic maintainer is mainly designed and manufactured based on the harm of voltage distortion in power distribution network to user equipment. it is mainly aimed at relatively delicate electrical equipment in power distribution network, such as computer control system crash, PLC control, nuclear magnetic resonance instrument high-precision equipment, etc. regarding this load, the common practice is to install "active filter". this function is understandable, but the cost is too high. Based on this, our company uses foreign advanced technology to separate our practical experience and successfully develops a multi-function harmonic maintainer.

How to weigh the main indicators of power quality
How to weigh the main indicators of power quality: power as a commodity, quality is the scale of weighing its value, different people have different understanding of power quality. So, what is power quality? How to weigh the main indicators of power quality? Power quality, in a general sense, refers to high-quality power supply, including voltage quality, current quality, power quality and power quality. Weighing the power quality of the label includes: voltage bias, frequency bias, voltage three-phase imbalance, harmonics and inter harmonics, voltage shake and voltage flicker.
