英文摘要:

      An application example of the magnetic saturation feedthrough sensor for leakage protection is described.Magnetic saturation sensor is a precision sensor which is mainly used for AC and DC current signal detection，such as sensor current，voltage transformers，leakage protection and other industrial applications.Magnetic saturation sensor uses the principle of magnetic saturation to generate a square wave oscillation，once the current signal passes，the signals from a few milliamp to tens ampere can be very accurately detected regardless of AC or DC.The leakage protection with detection principle of magnetic saturation sensor has a practical reference value.A final experimental result shows that the design expectations are reached.
