摘要
The ultra-high frequency partial discharge array sensor apparatus for a high-voltage power apparatus includes: a sensing unit which detects an electromagnetic wave partial discharge signal generated due to an internal defect of a high-voltage power apparatus and includes a plurality of sensors installed to detect information related to the position where the defect occurs; an anti-surge filter unit which prevents a surge input from the sensing unit; a signal delay time adjusting unit which equally adjusts delay times of signals input from the anti-surge filter unit; a signal switching unit which selectively transmits or blocks signals input from the signal delay time adjusting unit; a connector unit which connects a signal transmitted from the signal switching unit to the outside; and a sensor body which has a receiving space.
