Power Factor Correction 

As a business you will hopefully now be aware of the Carbon Reduction Commitment, The Carbon Reduction Commitment is a mandatory carbon emissions trading scheme that covers all organisations using in excess of  6,000MWh per year of electricity. There are solutions available to help you achieve your targets,Power Factor Correction being one of the most efficient solutions currently available.

Power Factor Correction is a measure of electrical efficiency, a typical power factor not utilising Power Factor Correction in most commercial and industrial organisations is around 0.80pf (80% electrically efficient) which in real terms means a 1000 Kva transformer can only supply an 800Kw load, a reduction in utilisation by approximately 20% which can also be applied to the switch gear and cables. By using Power Factor Correction  this problem can be easily corrected.

Power Factor correction targets the “inductive reactive currents” by intelligently introducing capacitors into the supply to counteract any inductive element of the load. Power Factor Correction can increase the electrical efficiency to around 1.00pf (100% electrically efficient)  

Power Factor Correction Will give some excellent Savings on your monthly utility bills, Power Factor Correction will also reduce circuit currents which will allow additional loads to be fitted to an otherwise inefficient electrical system. Be sure to take advantage of all the savings you could make by using Power Factor Correction

EnergyAce Voltage Optimisation

What is the EnergyAce - Voltage Optimisation

EnergyAce is manufactured in the UK and is a highly efficient power optimiser installed in series with the main incoming supply. It is usually connected via a circuit breaker and bypass switch arrangement.

EnergyAce works by carefully controlling the voltage and reducing the overall energy consumption of a site by reducing kw/h consumption without any detriment to plant and operations.

EnergyAce works by carefully controlling the voltage and reducing the kw/h consumption of a site without any detriment to plant and operations.

EnergyAce is supplied as standard with web enabled monitoring software, which will allow you to monitor a sites power usage form anywhere in the world via an internet connection

EnergyAce is available with additional bolt on benefits to help improve the electrical efficiency to around 99%

EnergyAce is available with the additional bolt on benefits of Active Harmonic Filtering to ensure that a site complies with the latest Electricity Council's recommendations regarding harmonic distortion

EnergyAce Benefits and Savings

  • Reduces energy consumption by up to 20%
  • Reduces carbon emissions (see latest CRC legislation)
  • Reduces circuit currents
  • Reduces harmonic distortion
  • Reduced Maximum Demand and Capacity Charges
  • Improves electrical efficiency (power factor)
  • Improves plant utilisation
  • Extends the life of electronic components and plant
  • Protects from Transients Spikes & Surges  

EnergyAce Light technology reduces energy across a number of disciplines although in some applications like Storage Facilities, Parking Facilities and Operations that rely on a high degree of lighting, the main reduction of energy may be gained from optimising the lighting circuits alone to maximise a return on any investment by targeting the areas that would benefit the most.

EnergyAce technology does not work as effectively on some types of load. Maximum savings are usually gained on the more common inductive and lighting loads generated within an industrial or commercial environment and are far less likely to return any substantial savings on resistive and VSD loads, it is therefore important to understand the load profile of each individual site to ensure the predicted guaranteed savings are realised.

Harmonic Filters

The AHC Range of Active Harmonic Conditioners from Power Efficient Systems are available for use with a number of applications and are specifically designed to reduce the Current and Voltage distortion due to Harmonics.

Harmonics are generated in the main by non-liner loads (Thyristor Drives - Variable Speed Drives etc.) on a consumers installation, this could lead to a number of undesirable effects as detailed below:
  • Nuisance Tripping of circuits
  • Unexplained failures of electronic circuits & associated drives.
  • Malfunction of control systems.
  • Overload of capacitors and associated systems.
  • Excessive heating of transformer, switchgear and cables.
  • High neutral currents leading to neutral "Burn Out"
  • Interference of computer systems and telecommunications.

PES offer a complete solution to harmonic problems from the investigation of harmonic interference, identification, design, manufacture and the installation of a purpose built filter.
Sized correctly for the application, Active Harmonic Conditioners from Power Efficient Systems can remove all the aforementioned concerns and help to ensure compliance with the required standards for connection to an electrical utility supply. Commonly known as G5/4-1.

Surge Suppression

Power Efficient Systems Ltd offer a range of surge suppression solutions including class I & II combined lightning & surge suppression (T1 & T2) and class II surge suppression (T2)

Combined Lightning & Surge Suppression

This would normally be installed on the main incoming supply to plant irrespective of size, the unit is connected in parallel with the supply as close as possible to the incoming switch and main earthing point, this would protect the whole plant from externally born surges.

Supplementary Surge Suppression

This would Normally be installed on any sub circuits containing sensitive equipment to protect form any internally born surges and spikes etc, for example, this would normally be a sub distribution board supplying a computer suite or office.

Installation is similar to the Combined Lightning and Surge Suppression, connected in parallel with the distribution boards incoming switch / supply as close as possible to the incoming switch and main earthing point on the board to protect circuits connected to the board from other internally born surges and spikes.

Both systems can be supplied for single phase or three phase applications and are available in single pole, 2 pole, 3 pole and 4 pole versions either as a single plug in din rail mounted unit for installation within an existing distribution board that can accept plug in mcb`s or supplied in an enclosure for installation onto any type of distribution board.

PCB Disposal & Removal Polychlorinated Biphenyls

Power Efficient Systems Ltd offer a range of services to safely & legally deal with PCB contaminated oils and PCB capacitors form identification, preparation, removal and safe disposal.

PCB officially known as Polychlorinated Biphenyls was first introduced as an insulating oil and was widely used in the manufacture of capacitors and transformers through the 1950s and most recently in the UK up to 1978
Polychlorinated Biphenyls, PCB capacitors were manufactured in the UK between 1958 and 1978 although the import of Polychlorinated Biphenyls PCB capacitors only ceased around 1982.
Identification can be difficult although our experience and detailed knowledge of the many trade names associated with Polychlorinated Biphenyls normally would enable an accurate and true identification.
Were identification cannot be verified or an accurate date of manufacture cannot be verified through detailed paperwork or where the find is small and uneconomical to carry out testing procedures on the oil, the find should be treated as contaminated and dealt with accordingly.
PCB capacitors were effectively banned at the end of 2002 although as in many cases, isolated finds do still occur which warrant immediate specialist disposal.
There is very stringent legal legislation covering the movement & disposal of PCB which must be adhered to in order to avoid prosecution.
Polychlorinated Biphenyls PCB Characteristics & Effects
  • PCB is non biodegradable and permanent in the environment when exposure occurs
  • PCB is absorbed by the skin, can be inhaled and can be accidentally consumed via hands
  • PCB causes Liver Damage, Cancer and Increases Blood Fats leading to Heart Disease.
  • PCB can cause a severe rash called Chloracne
  • If involved in fire, PCB creates Potychlorinated Dibenzoflurons and Potychlorinated Dibenzodioxins, both much more deadly than PCB alone and likened to Cyanide Gas.
  • Once identified, the fire service may not enter a building with PCB contamination, instead they may contain the fire only
  • A PCB fire can cause permanent long lasting contamination of surroundings leading to a termination of business, litigation and possible death of personnel.
