How to deal with the power factor of the low voltage system in advance

The power factor is ahead of the penalty Oh! Hehe, but I want to know what device you know the power factor is ahead of time! If you don't have this penalty on your electricity bill, don't worry, it's likely that your meter wiring is wrong!

Generally, a power factor meter is installed on the inlet cabinet; Since the power factor is ahead of time, it must be equipped with a non-supply compensation device! There is also a power factor display on the reactive power compensation controller, if the two values are compared, if it is indeed ahead, it means that there is a problem with your reactive power compensation device, there is overcompensation, and too much capacitance is in operation for a long time! This is to check whether your reactive power compensation device is normal!

The solution is to keep your power factor in between. It's best to deal with the problem first, it's a bit messy to say!

I don't understand, you're saying you're ahead of the curve? Or do you want to get him ahead of your time? It should be that your power factor is ahead of your time Then don't listen to the nonsense upstairs The power factor lags There should be a few capacitors in parallel, yes, but if you are ahead, it means that your capacitors are a little bit more Remove a few.

Due to the existence of inductive load, the power factor of the power system is low, and the reactive power occupies the transmission capacity and leads to the voltage decrease. The solution is to install capacitors and implement reactive power compensation.

Why in a low-voltage system, the power factor is reduced.

Hello dear. In the low-voltage system, the main reasons for the reduction of the power factor are as follows: the motor load is unbalanced

In a low-voltage system, the electric motor is the main load device. If the load of the motor is unbalanced, the current waveform will be deformed, resulting in a decrease in the power factor. Insufficient reactive power compensation:

There are a large number of inductive loads in low-voltage systems, such as inductors, transformers, etc. These devices generate reactive power, which reduces the power factor. If the reactive power compensation in the system is insufficient, the power factor will decrease.

Excessive line resistance: The resistance of wires and cables in low-voltage systems is relatively large, and excessive line resistance will lead to a decrease in voltage, which will increase the current and decrease the power factor. Use of power electronics:

The power electronic devices in the low-voltage system, such as frequency converters and power regulators, will generate harmonics, which will cause the power factor to decrease from the muyu hole. In summary, the reasons for the reduction of power factor in low-voltage systems are complex, and comprehensive analysis and optimization of the system are required, including load balancing, reactive power compensation, and line virtual seepage design.
