Abstract

A power measurement cell comprises at least one thermoelement (30) and at least two heating elements (20, 21, 25). A first heating element (20, 21) can be heated by a measurement signal. A temperature can be measured by means of the thermoelement (30). The two heating elements (20, 21, 25) have a very small spacing. The at least one thermoelement (30) and the two heating elements (20, 21, 25) have a high thermal coupling.
