Abstract

An electrical apparatus, including a first housing having a fluid-filled or fluid-perfused wet space and a dry space that are separated from one another by a wall, wherein the wall includes an opening, one or more power-conducting and/or power-switching elements arranged in the wet space, and a control electronics for the one or more power-switching elements arranged in the dry space. The electrical apparatus includes a second housing extending from the opening into the wet space, wherein the second housing reaches up to or encloses a power-conducting element, and a sensor arranged in the second housing, the sensor being configured to measure a variable that depends on an electrical power flowing through the power-conducting element. The second housing seals the opening in the wall in a fluid-tight manner. Measured values or signals of the sensor conducted by lines are passed through the opening into the dry space.
