IMPROVE POWER FACTOR USING CAPACITORS BANK

power factor or factors work is the comparison between the active power (watts) to apparent power / total power (VA) or the cosine of the angle between the active power and apparent power / total power. high reactive power will increase this angle and a power factor will be lower. factor power factor is always less than or equal to one.

IMPROVE POWER FACTOR USING CAPACITORS BANK

in general, the electric load consists of a heater jaringa, neon, an electric motor-Laini other so mostly electrical load is an inductive load. to eliminate / reduce inductive power components is required capacitor or capacitor bank.
The main function of capacitor banks:

1. Capacitor banks eliminate penalties / excess costs (KVARH) 
2. Avoid overloaded transformers
3. Provide additional power available
4. Avoiding the increase in flow / temperature on the wire
5. Capacitor bank serves to maximize the use of power (kVA)
6. Saves power / efficiency
7. Avoid the Line Voltage Drop
8. Preserve installation & Electrical Equipment
9. The capacitor bank also reduce losses - other ruugi on electrical installations

Judging from the way it works, capacitor banks can be divided into two:
Fixed type capacitor bank, by providing capacitive load that remains despite changes in load. Typically used in such a direct load on the induction motor. Safe value is 5% of the motor capacity, consideration is currently no load conditions.

Automatic type, providing capacitive load that varies according to load conditions. This type of panel is equipped with a Power Factor Controller (PFC) as reference www.circutor.com. PFC will keep cos phi network according to the specified target. To load fluctuates with Static Var Compensator quickly used type (SVC) which uses Thyristor as switchernya. As for the load fluctuations are not too quick to use Dynamic Var Compensator using Magnetic Contactor and relay PFC as a switchernya.
