Operating electrical equipment at higher and lower than optimum voltages leads to significantly higher energy consumption and possible damage to electrical lights and appliances.

Over voltage supply creates four detrimental situations:

1. You use and pay for more electricity than you need.
2. Your appliance works harder than it should and will therefore wear out faster.
3. You will produce more carbon emissions than you necessary.
4. Poor or bad power Harmonics can cause severe damage to new electronic/electrical devices and at least shorten the life expectancy of the device.

Under voltage supply creates three detrimental situations:

1. Some appliances will fail to operate if the voltage is too low.
2. Your appliances will demonstrate various types of malfunction such as a poor quality picture on a television; clothes not being washed or dried correctly, vacuum cleaners not cleaning correctly, steam irons not getting hot enough, electric water heaters taking far too long to heat the water etc.

3. Some of your electric motors will overheat as they are not running at the correct voltage (especially washing machines, dishwashers, boiler pumps, fridges etc) and will wear out much faster and have much shorter lives.

Why does over and under voltage occur?

Over and under voltage is generally a chronic problem aggravated by a number of factors beyond the end user's control. Electric utilities try to maintain voltage levels delivered to customers at ±5%. However, factors like weather, high demand and others can cause the utility voltage to fall within a ±10% range. Even under ideal conditions, most customers will see a drop in utility voltage levels over the course of the day as demand begins to increase around 8 AM and peaks around 3 or 4 PM.

Distribution system characteristics can also contribute to chronically low voltage situations. For example, customers at the end of a long distribution line may be subject to a permanent voltage drop due to line losses on top of the utility voltage variations.

PropSava Protection:

The PropSava protects all electrical equipment in the property from the ills of over and under voltage. It reduces the electrical cost of using electrical appliances and protects all the appliances from the damage caused by both over and under voltage.

Electric costs could be reduced by up to 17% and the life expectancy of the electrical equipment in the property could be increased by up to 25%.

"A 230V linear appliance used on a 240V supply will take 4.3% more current and will consume almost 9% more energy. (UK Electricians Guide 16th Edition BS7671)

PropSava and Security of Supply:

A PropSava will optimise the power supply to the entire electrical load of a property because it is installed at source.The PropSava has been designed with no moving parts. Voltage optimisation and power quality improvement is achieved through magnetic fields only, and the unit is as reliable as the incoming power supply itself. The unit requires no maintenance, is guaranteed for 10 years and will last for 25- 40 years.The PropSava has been field tested for two years and is efficient across its entire operating range.

What the PropSava does for Lighting:

Lighting loads tend to be switched on for a large proportion of the time, so savings on lighting equipment are very valuable.

"A 230V bulb used at 240V will achieve only 55% of its rated life. (UK, IEE Electricians Guide)

The Environmental benefits of the PropSava:

Over-voltage is an under-publicised cause of power supply inefficiencies. The PropSava can reduce emissions by up to 17%. We estimate that up to 90% of European businesses suffer from over-voltage and would save energy by installing a PropSava. The contribution towards Europes carbon-cutting effort over the coming decades will be substantial. In addition, a PropSava prolongs the operating life of electrical equipment, reducing non-recyclable waste.

PropSava Savings:

Based on the UK national average voltage (242V), the average optimisation level of a PropSava is 8%, this typically produces power consumption in Kilowatt per hour savings of 13%. However, as the supply voltage does vary slightly across the country and each site will have different power consumption, savings can be seen between 10 - 17% on around 90% of UK

homes and offices.

Slightly lower figures can also be achieved in Europe with the average optimisation level at 6%, Kilowatt per hour savings of 9%, savings can be realised between 8 - 12% on around 70% of

European homes and offices.

Installation:

A qualified electrician must be used to make the installation of the PropSava. The PropSava can be installed inside or if outside the property, in a waterproof box system, as near as possible to the electric meter. Normal internal installation could take up to 1 hour.

Safety Certification:

The PropSava device is CE marked, and complies with EN55022, EN55024, 61000-3-2, 61000-3-3, IEC60950. It is also undergoing UL/cUL listed product status for North America (UL 508, Industrial Control Equipment), and also undergoing Japanese (PSE/GSL) and NATA (Australian and S.E. Asian) and CCC (China) accreditation.
