DEVICE FOR RECORDING ALTERNATING COMPONENT OF CURRENT IN POWER SUPPLY SYSTEM OF VEHICLE

摘要

FIELD: measuring technique. ^ SUBSTANCE: device comprises current pickup made of toroidal inductive coil with ferromagnetic core, discriminator, alternating current amplifier, synchronous detector, direct current amplifier, and indicator. The second input of the synchronous detector is connected to the armature of the generator of the alternating current through the phase-shifting circuit. ^ EFFECT: expanded functional capabilities. ^ 1 dwg
