By introducing the applications of static self - shunt excitation system in the 100MW steam turbo- generators of FenYi Power Plant, the great advantages of such excitation method are demonstrated.

Comparison on exciting modes of electromagnetic tomography sensor system;

This paper makes comparison and selection of the excitation modes and equipment in the hydropower station,and expounds the functions and features of the excitation system for the purpose of providing the reference for the designers of the excitation system of hydropower station.

In this paper excitation modes and control stra-tegies of levitation force winding for magnetic suspension bearingless motors are analyzed.

This paper presents case study how to increase performance ofeletromagnetic flowmeter It shows the experment results and anlysises in principle of theexciting mode of sensor, the steady of meter , conversion auuracy of signol.

Currently electromagnetic flowmeters generally adopt low-frequency square-waveform exciting mode, but sine- waveform exciting mode is also in consideration sometimes.

Currently electromagnetic flowmeters generally adopt low-frequency square-waveform exciting mode, which can not only erase polarization effect of electrodes generated by dc exciting, but also overcome orthogonal interference produced by line-frequency sinusoidal waveform exciting, the low-frequency square waveform exciting mode is widely used.
