In this paper the results of the experimental investigation of fiber optic electric fieId intensity sensors are presented. These sensors are based on electroluminescent effect which consists in the light emission by some substances placed in variable electric field. The luminescent effect is observed in some composite semiconductors, among other - ZnS, doped by Mn, for high its concentration, order 10 -4 -- 10 -3 g/g. The final aim of this investigation will be the elaborafion ofan electric intensity sensor, which together fiber optic temperaturę sensors and intensive of magnetic field sensors make possible, in the future, to monitor the state ofwork of electromagnetic power arrangements, first ofall - high voltage power transformers.
