A pluggable high-voltage feed-through has an inner conductor, which extends in a longitudinal direction between a high-voltage connection and a plug-in section of the high-voltage feed-though. The plug-in section is configured for plugging the high-voltage feed-though into a device connection part of an electrical device. An insulating body surrounds the inner conductor. A test tapping point is provided with an electrical contact for connecting to a connection of a measuring device. The test tapping point is arranged outside the plug-in section. An electrical device has a fluid-tight housing and the high-voltage feed-through. A device connection part is provided for receiving and contacting the high-voltage feed-through.
