Input Waveform Output To Customer A voltage sag/swell in the utility waveform is seen by the customer without a Custom Power Device in the substation Sags and swells can have severe affects on the Customer Load Implementing the Customer Power Devices into the substations will correct the waveform

Dynamic Voltage Restorer Power electronic converter injects appropriate voltage Acts as a buffer, used for injecting or absorbing Can Compensate a 50% three phase voltage dip for up to 50 cycles Cover a power range from 3MVA up to 50 MVA

SMES Superconducting Magnetic Energy Storage Instantaneous discharge Unlimited duty cycles Response time of.5 ms Ride through a 2.5 sec sag 100% recharge in 120 sec Very mobile

STATIC TRANSFER SWITCH Protects against sags and interuptions Seamless transition between switches For facilities where load is power sensitive For facilities with loads above 3MW Cost effective for both the utility and the customer

FLYWHEEL Deliver higher power per weight and size Cycles many thousands of times Have a precisely known state of charge Have a long life Operate without using potentially hazardous materials
