The Four Main Functions Of Parallel Capacitors

1 can improve power factor
Due to the high inductive load and reactive load of electrical equipment. In order to ensure the normal operation of the equipment, the reactive current provided by the distribution transformer is relatively large, which may cause overheating of the electrical equipment and threaten the safe operation of the electrical equipment.
2 can reduce line losses
In general, the voltage loss of power transmission equipment is proportional to its impedance. When reducing the number of transformer stages, increasing the line cross-section, using cable power supply, and adjusting the capacity of capacitors appropriately according to load changes, the voltage loss can be reduced, achieving the effect of narrowing the voltage deviation range.
3 can filter high-frequency signals
In circuits that require filtering high-frequency signals, the total capacity of capacitors connected in parallel is equal to their sum, but the effect is better than using a single capacitor because it can reduce distributed inductance and achieve high-capacity filtering of high-frequency signals.
4. Convenient to use
Parallel capacitors are used for reactive power compensation and connected to the power grid. When the capacitors fail due to electrical equipment, they can be disconnected without affecting the system's power supply.
