Power Factor Correction Unit

Power factor correction is proven to reduce site wide energy costs and power demand

The EnergyAce range of Power Factor Correction systems have been designed to address the challenges found in many of today’s diverse power needs and encompass many years of development and experience to deliver reliable and cost effective energy saving solutions world-wide.

There are five main types of power factor correction and it is important to understand which type is best suited for your type of loads to ensure many years trouble free operation and maximum impact.

Standard EASTPF Range Our most cost effective range and suitable for sites with low Harmonic Pollution.

De-tuned EADTPF Range Designed to be used in the toughest of environments, EnergyAce De-tuned Power Factor Correction units utilise heavy duty detuning reactors to 189Hz and 525v capacitors to offer unrivalled performance and reliability in arduous environments where harmonic distortion is expected.

Real-time RTPF Range Our Real Time PFC can be configured as either Standard or De[1]tuned and designed for sites with highly fluctuating loads. Our Realtime units can react to the load in 10ms to ensure Power Factor is at the optimum level at all times and demand remains as low as possible.

Hybrid HYB Range Our Hybrid PFC-AHF units are a combined Power Factor Correction and Active Harmonic Filter Solution. Designed for sites with high Harmonic Pollution, the EnergyAce Hybrid PFC- AHF solution compensates for both reactive Power and harmonic distortion in a very cost effective and compact manor.

Static Var Generators SVG Range Static Var Generators offer real time power factor correction

of both capacitive and inductive reactive power. SVG offer correction on both balanced and unbalanced three-phase systems and are ideally suited for highly fluctuating loads whether inductive or capacitive, typical applications include correction of Solar PV installations, lifts, welding equipment and data centres.

Bespoke arrangements are available on any of our systems including single phase power factor correction.

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 generally applied to energy bills when a site operates on a power factor below 0.95pf (95% efficient) in the form of a Reactive Power charge although any power factor less than 1.00pf 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 like motors.

Motors can come in many forms, machines, conveyors, mixers, compressors, HVAC, escalators, lifts, all these can be considered as motors and an inductive load that in most cases will require some form of automatic power factor correction.

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. 

In countries with a developing electrical network and economy, 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 .      

EnergyAce formed in 2002, have a range of power factor correction systems designed and developed in association with Vishay a world leader in capacitor manufacture and design, our expertise is reflected with many decades of internal experience and award winning business performance.

Many modern electrical equipments 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
