Voltage Sags in Three-Phase Systems

It is argued that solving the voltage sag problem requires cooperation between utilities and end-users, with support from equipment manufacturers and standards-setting organizations. It is possible to make better equipment when the demand for it is high enough. Standards are needed that guide utilities, end-users, and equipment manufacturers. It is also important that everybody becomes aware of voltage sags as a potential problem. Education of electrical and mechanical engineers is very important to achieve this aim.
