Abstract
A power component includes two electric terminals, a component housing, a main component at least partially surrounded by the component housing, connected with the two terminals, and configured to carry a power current flowing between the two electric terminals, and a sensor and emitter unit which is configured to measure a value of a physical quantity (T, V, ΔV) characterizing an operating state of the main component, and to emit an electromagnetic signal, in which the measured value of the physical quantity is encoded. The sensor and emitter unit includes an antenna for emitting the electromagnetic signal which is spaced apart from the main component and arranged in, on and/or at the component housing.
