Compared with traditional IEC method,the wide bandwidth pulse current method could get more information about partial discharge,which will be helpful to improve the sensitivity as well as the ability of anti-interference.

Partial discharge detection system based on very wide bandwidth pulse current method

Research on the UWB EMP Effects of Radio Fuze;

By the irradiation experiments of ultra-wideband electromagnetism pulse(UWB EMP) to radio fuse,the effects of radio fuse are studied.

It is found that they are the same in the neighbourhood of z-axis for narrowband pulses, but in the case of broadband pulses, singularities emerge near z-axis for pulsed beams obtained by using complex amplitude envelope representation and only complex ana.
