To improve the power factor it is required to connect a fixed capacitor or capacitor bank.

How capacitor bank works pdf. For example when 51 mega var capacitor bank is to be commissioned in an 11 kv system each unit of the bank is made of 11 kv rated. Every user which utilizes electrical power to obtain work in various forms continuously asks the mains to supply a certain quantity of active power together with reactive power. The capacitor unit is made up of individual capacitor elements arranged in parallel series connected groups within a steel enclosure.

The capacitor unit fig. The power factor will be very low under such situation. Power factor and use of capacitor banks.

1 is the building block of a shunt capacitor bank. Sizing of capacitor banks for power factor improvement the power factor correction of electrical loads is a problem common to all industrial companies. Distribution transformers which works on the principle of electro magnetic induction consume reactive power for their own needs even when its secondary is not connected to any load.

A capacitor bank is a grouping of several identical capacitors interconnected in parallel or in series with one another. The internal discharge device is a resistor that reduces the unit residual voltage. For high voltage applications numbers of capacitor units are connected in series and parallel combinations to form a capacitor bank for required voltage and kilo var ratings.

These groups of capacitors are typically used to correct or counteract undesirable characteristics such as power factor lag or phase shifts inherent in alternating current ac electrical power supplies. The variable capacitors shown in fig. Capacitor banks is a cost effective manner to increase capacity but as the voltages change within the distribution range the optimum placement sizing and fusing technology of the capacitor banks also changes.

How three phase electricity works the. Usually fuses are used to protect capacitor units and they may be located inside the capacitor unit on each element or outside the unit. Shunt capacitor banks reduce current electrical loads have a combination of both active and reactive power.

A shunt capacitor bank or simply capacitor bank is a set of capacitor units arranged in parallelseries association within a steel enclosure.
