According to the Code for Design of Shunt Capacitor Devices, when the power grid harmonic is mainly 3 times or more, it is generally 12%; 4.5%~6% and 12% reactors can also be used according to the actual situation: (1) The third harmonic content is small, so 0.5%~1% series reactor can be selected, but check whether the third harmonic amplification after the capacitor is put into operation exceeds or approaches the limit value, and there is a certain margin. (2) The third harmonic content is large and has exceeded or approached the limit value, so 12% or 4.5%~6% series reactors can be used for mixed installation.

Dry goods | What is power quality? Do you really understand?
2021-12-31
The IEC (1000-2-2/4) standard defines power quality as the physical characteristics of power supply devices that do not interrupt or interfere with users' use of power under normal working conditions. Strictly speaking, the main indicators to measure power quality are voltage, frequency and waveform. Generally speaking, it refers to high-quality power supply, including voltage quality, current quality, power supply quality and power consumption quality. Just as there are good and bad commodities, there is also a quality problem with the electric energy we usually use. High quality electric energy can not only reduce the loss of electrical appliances and lines, improve the use efficiency of electric energy, but also ensure the stable and healthy operation of the power system, thus greatly reducing the related indirect risks and losses.

Why should capacitance compensation be carried out for low-voltage cabinet?
2019-10-18
In the low-voltage power distribution part, there are incoming cabinet, outgoing cabinet, and of course, capacitor compensation cabinet. What is the role of capacitor compensation cabinet? As the name suggests, it is to play the role of capacitor compensation. Let's first look at the principle of capacitor compensation. During capacitor compensation, the capacitance and load are connected in parallel. The capacitance is the same as the power store. When the load increases, the output voltage of the power supply will drop due to the internal resistance of the power supply, Since the two ends of the capacitor need to maintain the original voltage, that is, a part of the electric current in the capacitor will flow out, delaying the downward trend of the voltage, that is, the principle of capacitor compensation.
