FIELD: measurement.
SUBSTANCE: invention relates to technique for measuring electrical currents and can be used to calibrate and study characteristics of non-contact fiber optic electric current sensors based on BSO crystals. Device for calibration of fiber optic sensors of electric current on BSO crystals contains source of radiation with power source, input and output polarizers located at crystal ends in rotary frames, AC voltage source, solenoid coil, photodetector module with integrated amplifier, is characterized in that power source for heating element is inserted into device, input collimator, output collimator, multimode fiber, computer, interface for communication with computer, heat-insulating casing, containing heating element, frame made of non-magnetic material, miniature temperature sensor.
EFFECT: invention makes it possible to improve calibration accuracy of these sensors.
