Sustainabilitylive! 2012 Seminar Programme - Smart 'Energy Hub' for improving efficiency

Electric appliances with inductive characteristics, such as refrigerators, air conditioners and compressors are more efficient when the voltage supplied is regulated and stabilised. PowerSines advanced voltage optimisation solution (the ComEC universal energy efficiency controller) saves up to 18% on inductive loads in commercial facilities by regulating and stabilising the supplied voltage level at the facility, extending electrical equipment lifetime and guaranteeing stable voltage output preset to the user-defined level. This presentation explains the physical principles behind voltage reduction on inductive loads using successful case studies depicting energy savings in leading industrial and commercial applications such as, cooling storages, refrigerated containers, commercial kitchens and supermarkets in the UK. Since Electricity Quality and Supply Regulations (EQS) define harmonized supply voltages across Europe at 230V±10%, utility companies are allowed to increase voltage levels to provide adequate voltages across existing infrastructures, resulting in shortened equipment lifecycle and wasted energy. The basic principle for voltage regulation reduces the voltage level from that of the incoming supply to a lower level allowed by EQC regulations. Voltage reduction, for inductive loads, in the range of allowed voltages results in increased efficiency, improved Power Factor and motor operation. Facility managers, electrical engineers, electricians, energy consultants, specifiers, electric designers, technical managers - and any business manager who needs to provide an energy efficiency solution for their company or customer in the commercial sector will benefit from understanding the ComEC solution for voltage optimisation, stabilisation and regulation. The UK success stories will hone in on similar cases relevant to audience members.
