LONG-TERM ENERGY SAVINGS GENERAL INFORMATION Legrand offers a comprehensive range of products and services that contribute to energy quality. By significantly reducing energy consumption, Legrand solutions have a positive environmental impact and are involved in energy efficiency. MORE POWER, LESS COST Based around reactive energy compensation, the Legrand offer reduces the amount of reactive energy supplied by the source and improves the power factor of the installation. Reactive energy compensation has the following advantages: FOR ALL - No billing of reactive energy - Reduction of active energy losses in the cables, given the current carried in the installation (almost 3%) - Improvement of the voltage level at the end of the line - Increase in the active power available with the same installation SUPPLIES FREE FROM INTERFERENCE Legrand offers a complete range of capacitors with detuned reactors and harmonic filters. Harmonics can damage capacitors and generate resonance on the supply or cause equipment to malfunction. Whether in an industrial or commercial building, Legrand products increase the service life of the installation while improving its energy performance. A SERVICE TAILORED TO YOUR REQUIREMENTS Legrand has a team of experts available to carry out on-site measurement in order to determine the most suitable installation, diagnose the quality of the electricity supply, and perform monitoring and maintenance operations for you. 4
LONG-TERM ENERGY SAVINGS (CONTINUED) Calculation example Installation of a 75 kVAr capacitor bank in a 1000 m 2 supermarket that wants to reduce its energy bills. INITIAL CONSUMPTION 192 kVA GENERAL INFORMATION LEGRAND CAPACITOR BANK A Legrand 75 kVAr capacitor bank is installed (compensation for a cos ø = 1) FINAL CONSUMPTION 168 kVA, i.e. -15% SAVING 192 kVA - 168 kVA = 24 kVA For a French billing system ("yellow" tariff) this represents a saving of 1128 €/year (1) . This saving also represents a reduction in pollution of 1.6 T CO 2 equivalent/year. (1) Prices and data not contractual. Calculated according to Environmental Impact and Management Explorer (EIME) software, Électricité de France model. 5
