fault localization
2.The cause of 500kV CVT damage during service was analyzed through test and fault localization. The resolving method for similar problem was raised and the aspect that attention should be paid during acceptance test at factory was pointed out. ?
3.According as the character of EHV transmission line fault transient current, based on the time and frequency localization character of wavelet transform.
4.The protection of power system is quick detection and localization of fault in order to act rightly and clear out the fault.
5.The character of EHV transmission line fault arc and its transient current is discussed, and the principle of non unit current transient protection is studied. Based on the time frequency localization and de noise character of wavelet transform, a new non unit current transient protection criterion based on multi resolution analysis is established.
6.By the cnd of 1980’s the wavelet analysis was applied in the areas of engineeringtechniques because of its excellent localization features in both time and frequency domains whichenables its zooming on high frequency parts of a signal and extracting fault signiture by usingwavelet transform.
7.This article angle has analyzed the higher professional technical education from CBE/DACUM "the electrical control technology" the curriculum ability localization, according to the higher professional technical education "the electrical control technology" the curriculum ability localization, point out the insufficiency and flaw existed in commonly used control electric appliance choice, electrical pilot wire road map, electricity control system installment, wiring craft, electrical control line fault diagnosis system approach, new starting velocity modulation equipment and control circuit, control circuit and main circuit aspect and so on.
