Principle Feature

Hall Effect Close Loop Current Sensor develops on the principles of the Magnetore sistive or Hall effects, and the null balance or zero magnetic flux method.
Primary current Ip provides the magnetic flux which will be balanced by a complementary flux produced by driving a current through the secondary winding, so the positive and negative magnetic field reaches balance to detect the current.
In other words, the secondary current, IS, creates a flux equal in amplitude, but opposite in direction, to the flux created by the primary current.This current can be expressed as a voltage by passing it through a resistor.
