How is the power quality from Phase Perfect better than utility supplied power?
Most electric utilities provide three-phase power in a “nominal” voltage specified within +/- 10%. Other users on the same distribution lines can affect the voltage supplied to you on each of the three legs of three-phase power by as much as 10% before the utility takes corrective action. Phase Perfect always balances three-phase voltages to within 1%. It also provides protection for three-phase equipment against over voltage, under voltage and single phasing. Protecting your equipment from these damaging situations on utility three-phase requires the purchase of special equipment.
