Reduced Voltage Starting This technique of starting the motor wired in a Wye connection, and later switching to a Delta Run connection, will dramatically reduce the current demand on a power distribution system. In areas where utility power is limited or over burdened, this system can reduce brown outs and severe voltage drops when a motor is started. The Wye Start/Delta Run method is not new to the industry. It is used on a limited basis in the US, and more widely used in European countries. Sometimes the method is mandatory on large motors. By using the Wye Start/Delta Run method, customers can achieve lower starting current demand. This starting method will minimize current demand during starting and reduce the impa..
