XLW Series Passive Zero Flux Leakage Current Sensor

A Zero Flux Leakage Current Sensor is a high-precision device designed for the accurate measurement of electrical current with minimal magnetic interference. It operates on the principle of zero-flux or magnetic compensation, using a secondary winding to cancel the magnetic field produced by the primary current. This feedback mechanism ensures that the magnetic flux in the core remains near zero, providing highly linear, stable, and precise current measurements for both AC and DC systems.
