Empirical Saving Measurements with PowerSines
To measure saving results in energy efficiency projects is not a trivial task. The modern voltage optimisation solution should not only control the voltage efficiently, but also provide a built-in mechanism for measuring saving results. With the rise in electricity prices, the readiness offinancial institutions to provide investments and the availability of government incentives for energy ...

How to prolong the life of your electrical equipment now more of us are working from home
The working world has changed as we know it. We are ‘zooming’ more, commuting into the office less and all working from home where we can. This change in working patterns has meant that we are using equipment and technology at home more than ever before. Rather than spending eight hours in the office each day using a business’s power for equipment such as computers, lights, ...

Voltage Optimisation can improve schools energy efficiency by up to 25%
Voltage Optimisation is a key component in any energy efficiency programme and could deliver up to 25% savings on electricity bills. In April the registration period for the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme will start again. Local authorities and companies with a portfolio of private schools will face sizeable fines unless they account for their energy use and make ...

Throw your electrical equipment a lifeline with the eco-max surge
As business starts to bounce back, the last thing anyone wants is expensive repairs or maintenance costs. When any electrical equipment breaks down, not only does it cost to fix but it also costs a business in productivity and output – making it a double hit to the pocket. This is where an eco-max surge can provide your business with peace of mind by adding a further layer of protection. ...

When lightning strikes, make sure your business and home are protected
Recently the UK has seen a surge of storms and lightning strikes across the country. With all the bad weather in the UK, we are used to it. But if you run a business that is reliant on a lot of electrical equipment, a lightning strike or a power surge can damage it and lead to it underperforming or in need of repair. You may think that lighting strikes are rare but the UK records between 200,000 ...

Voltage stabilisation of SMES VSI DC-link and compensation of reactive power by SMES using optimised switching strategies
This paper presents a novel and optimised switching strategy and control approach for a three-level two-quadrant chopper in a three-level neutral point clamped (NPC) voltage source inverter (VSI) superconducting magnetic energy storage (SMES). Using the proposed switching strategy, the voltage of the inverter capacitors in SMES can be independently controlled. Also, the minimum power and ...

Optimal integration of distributed generations for profit maximisation and voltage improvement including voltage rise issue
The integration of distributed generation (DG) at the load centres with the grid is a challenging task. This paper deals with the best location of DG as well as a proper share of loads between DG and grid that will yield the most economically efficient results. The optimal allocation of DG in distribution network is very common with an objective to minimise the losses. Loss minimisation is a good ...
