The invention relates to a device (10) for detecting partial discharges in a n electrical apparatus placed in a tank (1) filled with oil, wherein the tank wall is provided with at least one drain tap (4), wherein t he device comprises a probe (16) which is mounted on a carrier which is movable through the opened drain tap into the tank. The invention also relates to a method for detecting partial discharges in an electrical apparatus placed in a tank filled with oil, wherein the tank wall is provided with at least one drain tap, wherein a sleeve is initially placed on the flange of the drain tap and a carrier which is movable in the sleeve and on which a probe (16) is placed is subsequently moved through the opened tap until the measuring surface of the probe at lea st coincides with the inner surface of the tank wall, and the measurement is then performed. As a result of these two measures it is possible to test a transformer or other electrical apparatus for partial discharges, without the apparatus having to be taken out of operation.</SDOA B>
