Abstract: PURPOSE: An apparatus for measuring partial discharge of a high pressure rotator using a ceramic coupler is provided to perform a state sensing and maintenance/repair of the high pressure rotator by measuring partial discharge generation occurred in a stator winding of the rotator. CONSTITUTION: According to the apparatus for measuring partial discharge of a high pressure rotator, a ceramic coupler(300) detects an external noise signal and a partial discharge pulse where a commercial frequency component is removed from a stator winding of the high pressure rotator. And a partial discharge measurement unit(500) checks a state of the high pressure rotator by measuring the partial discharge pulse and the external noise detected from the ceramic coupler.
