sensor used in DC ground fault detection system according to measurement method can be divided into low frequency AC signal detecting and DC signal detecting of leakage current . It greatly affect the accuracy of the earth fault signal because of the existence of capacitance in the detecting of low frequency AC signal and it doesnt have online measurement DC current sensor in the market when we want to measure load leakage current. Caliper DC ammeter cant meet the requirements in DC system ground fault diction in terms of resolution, accuracy, range, on-line installation and on-line measurement.

Resistance Value

<p>Made up by the combination of InSb-In eutectic magnetoresistive (MR) components, the newly designed semiconductor film magnetoresistive current sensor (MRCS) was to detect weak current with its circuit controlled by signals. This kind of current sensor simultaneously alters the resistance value of two InSb-In magnetoresistive components. Through this way, it could eliminate the coupling capacitance of ultra-large capacity and reduce the volume capacity as well as improve the frequency characteristics. Set a specified parameter through accurate calculation, and make current generate signals which form direct proportion against the magnetic field generated by the weak current of magnetoresistive alteration, reaching the goals of detecting weak current. The test analyzed this current sensor’s operating characteristics with the testing pass bands as 7-1800 Hz. It was found that the weak current reached at 10 mA and could control the effect of temperature drift effectively.</p>

Splitting Effect

The splitting effect that is observed in microdiffraction pat-terns of small metallic particles in the size range 50-500 Å can be understood using the dynamical theory of electron diffraction for the case of a crystal containing a finite wedge. For the experimental data we refer to part I of this work in these proceedings.
