All mains powered electrical equipment are rated according to their power factor (electrical efficiency), a rating above 0.95pf (95% efficient) is generally considered as good efficiency with the maximum attainable being 1.00pf (100% efficient).
Penalties are usually applied to your energy bills when a site operates on a power factor below 95% efficient in the form of a Reactive Power charge although any power factor less 100% efficient will attract penalties in the form of higher energy bills.
The degree of electrical efficiency is improved by the introduction of power factor correction, a system that introduces power factor correction capacitors to counteract the negative effects of all types of inductive loads.
Power factor correction can considerably reduce circuit currents to allow for additional loads to be introduced to an otherwise overloaded electrical supply and in some cases negate the need for larger electrical supplies and infrastructure when expansion occurs.
Renewable generation can considerably benefit from power factor correction, the reduction of reactive power in the process of power generation with turbine technologies greatly increases export and reduces import of energy offering two opportunities to reduce overall energy costs.

Unstable networks
Where an unstable electrical network exists, a demand for power commonly outstrips capacity leading to the loss of electrical supply, brownouts and wild voltage swings power factor correction is vital in these circumstances to relieve pressure on the network.
Harmonics & Standard
Non-Detuned Capacitors
Many modern electrical equipment use thyristors, invertors and rectifiers e.g. to effect speed control of motors and temperature control of heater banks. Other power electronics are used in such items as UPS and battery chargers.
Such non-linear devices produce harmonic disturbance and can dramatically increase the current flowing in the system in addition to other harmful effects. Capacitors and other electrical devices can be damaged by these harmonics.
If you have any harmonic producing loads, please advise us so that we can ensure that your capacitors do not suffer as a consequence
