MEASUREMENT SYSTEM OF INDUCED CURRENTS IN RESISTIVE ELEMENTS OF ELECTROEXPLOSIVE DEVICE (EED) Russian patent published in 2018 - IPC G01R31/00 G01R19/04 

FIELD: measuring equipment.

SUBSTANCE: invention relates to an electrical measuring technique, in particular to measuring induced currents in a resistive element of an electric explosive device. Essence: the system comprises an induced current generation device, a duplex fiber-optic communication line, and an interface converter for communicating with a computer. Signal forming apparatus comprises a series-connected scale amplifier with a controllable gain, to the input of which through the commutator is connected the primary converter of the induced current, the module for extracting the absolute value of the signal, the peak detector and the analog-to-digital converter, the output of which is connected to the input of the optical transmitter, an optical receiver with a decoder of the control digital signal. Interface converter comprises a control signal driver connected to the input of the optical transmitter, and an optical digital receiver whose output is connected to a microprocessor for signal preprocessing and the formation of a high-speed USB interface.

EFFECT: improvement of measurement accuracy.
