FACILITY DERIVING ACTIVE COMPONENT OF CONDUCTION CURRENT Russian patent published in 2003 - IPC

FIELD: electric measurement technology. SUBSTANCE: facility includes source of testing voltage, voltage divider to which low voltage arm adjustable voltage amplifier is connected through first follower, capacitor and resistor. Output of voltage amplifier is connected to inverting input of adder, shunt connected in series with tested object is connected to noninverting input of adder through second follower. EFFECT: simplified procedure of deriving of active component of conduction current, increased operational safety in process of testing. 1 dwg
