FIBEROPTISKT METDON FOR METNING AV ELEKTRISKA OCH MAGNETISKA STORHETER

摘要

Fibre-optical measuring arrangement for measuring electrical and magnetic quantities. The measuring arrangement consists of a transmitter (G) and of an electronics unit (E) which are connected to one another via at least one optical fibre (11). The transmitter contains at least one optical absorption filter or interference filter and the electronics unit (E) contains at least two light sources (1, 2) having different emission spectra. The said optical filters are located in the beam path between the end face of the optical fibre (11) and a luminescence-capable layer of material (16) in the transmitter.
