Abstract

according to the invention, in an optical series connection consisting of a current-sensitive Faraday element (F) and an element (B1, Bi, Bn) which is sensitive to a component (E1, Ei, En) of an electric field, an emitted light signal (LS) is influenced such that its state of polarization and an optical property different from said state of polarization are modified. From this a first measured quantity (M11, M1i, M1n) is derived for the component (E1, Ei, En) of the electric field and a second measured quantity (M2) is derived for the electric current (I).
