摘要:The invention relates to a method for monitoring a capacitor bushing (1) to which an electrical operating voltage (UB) is applied and in which a voltage divider is formed with an electrically conductive inrt (4), whereby at least one measured value (UM1) of an electrical measured quantity (UM) is recorded and stored by using a measuring tap (7), which is connected to the inrt (4), and by using earth potential. The aim of the invention is to improve the method so that it is only slightly influenced by changes in the operating voltage. To this end, the impedance (ZE) between the measuring tap (7) and the earth potential is modified after recording the at least one measured value (UM1), and at least one signal value (US1) of a measurement signal (US) subquently formed is recorded and stored using the measuring tap (7) and the earth potential. The temporal interval between the time of recording of the measured value (UM1) and the time of recording of the signal value (US1) is measured in such a manner that a change in the operating voltage (UB), which potentially occurs between both times, is negligible. The invention also relates to a device for monitoring a capacitor bushing.
