In a sense, capacitors are a bit like batteries. Although they work differently, they both store electricity. If you have read about how the battery works, you should know that the battery has two electrodes. In the battery, the chemical reaction causes one electrode to produce electrons and the ot

Taking the power factor and voltage of the capacitor installation as the switching control basis, the capacitor operation area of the reactive power compensator can always be kept in the stable overvoltage range of 1.1 times. When the capacitor is put into operation, the power factor is lower than t

When the reactive power compensation device is designed and ordered, the parameters provided to the manufacturer are usually only the capacitance compensation cabinet type and the reactive power value. However, the two important parameters of capacitor rated voltage and static capacitance are often

Power capacitors and their main characteristic parameters power capacitors are the main components of reactive power compensator. With the development of technology and technological renewal, paper dielectric capacitors have been replaced by self-healing capacitors. Self-healing capacitors have bee

Insulation Resistance of Capacitance affected by temperature. In general, the insulation resistance of the capacitance decreases with the increase of temperature, and the decrease of the insulation resistance will lead to the increase of leakage current of the capacitance, so the working of the cap

Effect of temperature on Capacitor Life In general, the life of the capacitor is shortened with the increase of temperature, especially for the electrolytic capacitor. An electrolytic capacitor with a limit operating temperature of 85 ℃ can guarantee a normal working time of 181019 hours under the c

There are two reasons for the damage of the capacitor in the washing machine: one is that the washing machine is in the wet environment for a long time so that the capacitor gets dampened and the capacity decreases; The other is that the voltage of the power network is too high, which makes the capa

1. Relationship between capacitor loss and frequency. The loss of polar dielectric capacitors is determined by the dielectric and auxiliary media in the range of low and medium frequency. In general, the loss of conductance occurs in the range of low frequency. In the high frequency range, the loss

Capacitance. The capacitance of a capacitor is a parameter representing the capacity of the capacitor to store charges, which is numerically equal to the ratio of the charge quantity Q stored on the plate to the voltage U added on the plate. Capacity frequency characteristic. The dielectric constant

1. In the situation that surge current is formed repeatedly, the principle that the maximum instantaneous value of surge current and surge energy can not exceed the characteristic of pulse duration after varistor. 2. The varistor is not close to the heating and combustible device. It is suggested th
