Subject: Re: [TSSP] Racing arcs
Hi All, 2 more things to throw in pot. In all these mind-bending problems with arcing sparks we are looking for actually dangerous situations where field exceeds critical value 26~28 kV/cm. Ie. seems reasonable that such field is first to be blamed for inital trigering of racing sparks phenomena (wherever and whenever in system throut process ).Mechanisms and reasons,as we already know,are of various type. I wouldn't know wether the following is possible ,and if,to what extent:Some coilers do not ground their primaries,so is there possibility that whole primary conductor including secondary of power transformer could be electrostaticaly charged to say 20-30KV DC ? I was also wondering about how inaccuracy in winding of space wound coils affect transients tru secondary. For instance ,990 turns of 1000 turns secondary are separated with same distance ,but uncoutios coiler (who hasn't got winding machine) makes mistake and somwhere in middle of resonator 10 turns winds as if it were close wound system.
