PFI-Power Factor Improvement Panel
The power factor of a load is defined as the ratio of active power to apparent power, i.e. KW:KVA and is referred to as cos φ. The closer cos φ is to unity, the less reactive power is drawn from the supply.
* A reduction in the overall cost of electricity can be achieved by improving the power factor to a more economic level.
* The supply will be able to support additional load which may be of benefit for an expanding company.
* Reducing the load on distribution network components by power factor improvement will result in an extension of their useful life.
PFI-Power Factor Improvement Panel :- is known as the power factor of the load and is dependent upon the type of machine in use. A large proportion of the electric machinery used in industry has an inherently low power factor, which means that the supply authorities have to generate much more current than is theoretically required. In addition, transformers and cables have to carry this extra current. When the overall power factor of generating station’s load is low, the system is inefficient and the cost of electricity correspondingly high. To overcome this, and at the same time ensure that the generators and cables are not overloaded with wattles current, the supply authorities often offer reduced terms to consumers whose power factor is high or impose penalties for low power factor.
Reductions in power costs can be made by taking advantage of these special terms.
