摘要：A current measurement device is configured to measure electrical current in a
primary conductor that is electrically insulated from the current measuring device. Thecurrent measuring device includes a transformer with a saturable magnetic core formedwith a central aperture and a current measuring circuit. The electrical conductor in whichelectrical current is to be measured is disposed in the central aperture of the magneticcore. The current measuring circuit includes a current source driven by a voltage rampgenerator that is connected to the secondary winding in a direction opposite the flow ofelectrical current in the primary conductor. When the magnetic flux in the transformercore is equal and opposite the magnetic flux generated as a result of the electricalcurrent flowing in the primary conductor, the voltage of the voltage ramp generator isrepresentative of the DC or AC electrical current flowing in the primary conductor.
