I am keenly interested in any past and ongoing research in that topic, the one mentioned of the polarization of the dielectric dipoles. Kraig, do you recall exactly where you read about this ?
If anyone else has any knowledge or experience of this phenomenon of the recharging of the cable after...
Thank you all for your most excellent posts, I am aware of the phenomenon and the hazards and risks that it entails. I do not do this testing anymore myself, but am now gathering information for a research project, which information will help support/not_support a hypothesis involving energy...
Does anyone have an experience like this. You are in the field and you are dc hi potential testing some new ( or existing ) distribution shielded high voltage cables. You crank up the voltage on your test set, to whatever, say, 25,000 volts dc, and take your readings of the leakage current as...
I guess the key here is to run the supply through a reactor which you can saturate magnetically when you want, and leave normal when you want also. So you just put in series with the supply, and it acts as a very high impedance to current flow when you want to use it to block current, and a very...
Semiconductors can be used in conjunction with magnetic amps but magnetic amps are not semiconductors themselves. Normally they consist of inductors and and/or transformers, in some arrangement to perform some signal modifications. See, for instance...
Since the mag amps are so rugged and handle transients so well, I am considering using them in lieu of semiconductors to rectify sinusoidal ac waveform. My question is, is this possible, and if so, can you point me in the direction to go study how to design it ?
Thank you.
