功率因数降低会让电能传输产生巨大损耗，而且电压损耗受无功功率影响，同时

The reduction of power factor will cause huge loss of electric energy transmission, and the voltage loss will be affected by reactive power. At the same time, it will also reduce the utilization rate of power equipment, wasting energy and economy. Therefore, according to the relevant regulations of the power supply department, it is necessary to limit the power factor. In some power supply areas, a certain value needs to be reached, and below the specified value, reactive power compensation must be performed. <br>The standard of natural power factor of ordinary residential area is 0.7-0.75. However, the power factor of residential electricity should be maintained above 0.9. When the power factor does not meet the requirements, it is necessary to increase the power factor, and the method of improving the power factor can be correctly selected and the motor is used reasonably so that the motor does not run at light load or no load. The transformer capacity can be selected reasonably, and the operation mode can be adjusted appropriately to avoid the light or no-load operation of the transformer

A lower power factor can cause a huge loss of power transmission, and voltage loss is affected by reactive power, but also reduces the utilization of power equipment, waste energy and economy. Therefore, according to the relevant provisions of the power supply sector, the need to limit the power factor, in some power supply areas need to reach a certain value, below the specified value must be reactive power compensation. <br>The natural power factor standard for ordinary residential areas is 0.7-0.75. However, the power factor of electricity consumption of residents should be maintained at more than 0.9. When the power factor does not meet the requirements, to improve the power factor, the method of increasing the power factor can be selected correctly and the reasonable use of the motor, so that the motor does not light load or empty operation. Transformer capacity can be selected reasonably, the mode of operation can be adjusted appropriately, and the transformer can be avoided from light or empty operation

The reduction of power factor will cause huge loss of power transmission, and the voltage loss will be affected by reactive power. At the same time, it will also reduce the utilization rate of power equipment, waste energy and economy. Therefore, according to the relevant regulations of the power supply department, it is necessary to limit the power factor, reach a certain value in some power supply areas, and make reactive power compensation if it is lower than the specified value.<br>The standard of natural power factor of common residential area is 0.7-0.75. But the power factor of residential power should be maintained above 0.9. When the power factor does not meet the requirements, it is necessary to improve the power factor. The method to improve the power factor can correctly select and reasonably use the motor, so that the motor does not operate under light load or no-load. The transformer capacity can be reasonably selected and the operation mode can be properly adjusted to avoid light load or no-load operation of the transformer<br>
