NON-INTRUSIVE SIGNAL COUPLING APPARATUS AND METHOD FOR MV POWER LINE COMMUNICATION

摘要

PURPOSE: A contactless signal coupling device and method thereof are provided to remarkably remove the size and the weight because magnetic saturation about high current does not occurs. CONSTITUTION: A first half body(17) and a second half body(18) are combined to a toroidal type. A center line with an inner wire is coupled which is connected to an external site communication device in non contractive. A core inside a first half body and a core inside the second half body are connected. A coil covers the core inside a first half body.
