On the basis of establishing primary and secondary arc models of transient fault and by use of DB6 discrete wavelet,the multi-resolution analysis on voltage signal of faulty bus is performed,and the spectrum energy of its high-frequency component within specified time window is calculated.

Capacitor voltage transformer(CVT) contains capacitors and nonlinear inductances,so primary-side isolator operation may cause abnormal secondary voltage to influences normal operation of relay devices in substation,or even to lead misoperations of over-excitation protection for main transformers.

Experimental study on high-voltage and high-powersolar array secondary discharge;

The effect of the secondary discharge overlapping on ozone generation was found to be important.

This paper discusses the charging and discharging effects on high-voltage solar array with focus on the physical process of electrostatic discharge and secondary discharge.

The conventional TEM data processing and interpretation methods are through conversion formula inversion of field collected normalized secondary potential data into apparent resistivity values and then focused on each target to plot apparent resistivity contours,and through analysis and interpretation of plans to circle out anomalous regions.
