. A current sensor measures alternate (AC) as well as directly (DC) the flow of current. It does this by using the magnetic field to detect and then produce an output. They quantify active current without interfering with the circuit.

If electric current flows through a conductor it generates a magnetic field proportional to the dimensions of the conductor itself. The magnetic field generated is utilized by current transformers for determining the direction of electric current.

A AC sensor’s inner core is wrapped around wire. When current passes through the conductor, it generates an electromagnetic field which produces an electrical discharge in the wire contained within the sensor’s current. A DC sensor is able to perform the same function but depends upon Hall effect innovation for its efficiency. A central component, Hall effect equipment, along with transmitter and receiver circuitry are the three parts of the Hall effect detector.

Current transformers are vital in many areas, including sub-metering. This is when the energy consumed by tenants is independently tracked. They aid with control of regulations and cost reduction by providing data about usage of energy. 7fetjyrbbl.
