FREQUENTLY ASKED QUESTIONS

WHAT ARE THE CONSEQUENCES OF A HIGH VOLTAGE FOR MY BUILDING?

A high voltage has a negative impact on two levels: first, the electricity bill will be higher and second, the lamps and electrical engines in the building will heat more, which may reduce their lifespan by half.

WILL I STILL HAVE ENOUGH POWER IN MY BUILDING WITH A VOLTAGE STABILIZER?

Yes, there is no loss of comfort for the user and  you will not notice the difference: all your electrical lamps and devices will work normally with a stabilized voltage at 210-215 volts.

HOW DOES A VOLTAGE STABILIZER WORK?

The voltage fluctuates at the mains – typically in Europe, between 207 and 253 volts, according to the EN 50160 norm. Although it does not affect the functionality of the electric loads – designed to work within this range – it affects the electricity consumption. Stabilizing and reducing the electrical voltage directly saves energy and increases the lifetime of electrical devices and equipments.

WILL I ALSO LOWER MY CO2 EMISSIONS?

With a voltage stabilizer, the CO2 emissions will be lowered thanks to the direct and indirect savings. In Switzerland, with every kWh used, about 130g of CO2 are produced. If you can double the lifespan of all your electrical appliances, you will save all the CO2 linked to the manufacturing, distribution and transport of the appliances that you will not have to replace.

HOW MUCH WILL I SAVE WITH A VOLTAGE STABILIZER?

By lowering the voltage at 210-215 volts, your peak power use will be lower and your electrical devices will be more efficient : this is the direct average saving of 10% on electricity. With a lower tension in your building, all your electrical appliances will be protected against voltage peaks and will also heat less, which can double their lifespan. This means that you may save 50% on your budget for repair, maintenance and depreciation of your electrical appliances.

HOW MAY I ESTIMATE MY RETURN ON INVESTMENT?

The return on investment depends on your direct and indirect savings potential, but also on your electricity price, that can cost the double depending where your building is located in Switzerland. The more you pay, the more electricity you use and the more appliances you have in the building, the shorter will be the payback period. The Typically, the return on investment of an optimal voltage stabilizer is lower than 5 years for a yearly consumption over 200'000 kWh.
