Abstract :
This paper presents the development and application of a three phase medium voltage static transfer switch system (MVSTS). The MVSTS is a 15 kV class switch system rated at a continuous current of 600 A. The function of a static transfer switch is to maintain AC electrical power to a critical load by switching between two independent power sources at speeds up to 4 ms. This switching time is sufficiently fast to preserve the operation of even the most sensitive customer equipment loads during distribution system disturbances such as voltage sags or voltage swells
