Power factor is an important technical indicator of the power system. It represents the ratio of active power to apparent power in an AC circuit. This ratio is usually expressed as a cosine function (cosφ). The size of the power factor reflects the energy utilization efficiency of the power supply output. If the power factor is too high, that is, the reactive power is too low, it will reduce the r...

First of all, the operation of inductive equipment must establish a magnetic field (such as a motor). Since the instantaneous start-up of large equipment requires the power grid to provide a large amount of Reactive Current to establish a magnetic field, the voltage of the system will be greatly reduced at the moment of equipment startup, causing other equipment to be protected or unable to operat...

The low-voltage power distribution system consists of a distribution substation (usually reducing the transmission voltage of the power grid to the distribution voltage), a high-voltage distribution line (i.e., a voltage above 1 kV), a distribution transformer, a low-voltage distribution line (a voltage below 1 kV), and corresponding control and protection equipment. Generally includes: Main equip...
