In most power applications, inductance prevails and reduces the amount of pay-load power produced by the utility company for a given size of generating equipment. The capacitor counteracts this loss of power and makes powerproduction more economical. Figure 2 – Pole-mounted capacitors. (a) Primary and (b) secondary
It is the job of capacitors to keep the power factor as close to 1 as possible. The power factor is an important essential of electricity. At this point, let it suffice to say that keeping the power factor close to 1 is a considerable economic advantage to the utility company and to the consumer.
The unbalance protection should coordinate with the individual capacitor unit fuses so that the fuses operate to isolate the faulty capacitor unit before the protection trips the whole bank. The alarm level is selected according to the first blown fuse giving an early warning of a potential bank failure.
Located in relevant places such as in the vicinity of load centers the use of SCBs has beneficial effect on power system performance: increased power factor, reduced losses, improved system capacity and better voltage level at load points. Shunt capacitor banks are protected against faults that are due to imposed external or internal conditions.
Inductance is the element in the circuit which is pulling the power factor below 1. Capacitance is the enemy of inductance. Therefore, capacitors counteract inductance, keep the power factor close to 1, and save money for the utility company. The capacitor usually consists of two conductors separated by an insulating substance.
In externally-fused SCBs, several capacitor element breakdowns may occur before the fuse removes the en-tire unit from service. The external fuse will operate when a capacitor unit becomes short-circuited, isolat-ing the faulted unit.
