somewhere a year ago he said he put it to work than after he burned his coils he never got it to work again,,,
somehow also from what i understood the resonance of the wires when open end it causes a reflection of that wave toward the source.. it will happen for a termination of higher impedance than the impedance of the choke... if it was shorted the wave also reflects but it does like an inductor does.. with reversed polarity... a pulse of reverse polarity would make the voltage zone to decrease its magnitude... even if it comes at the other electrode...is that correct?
I have a really good news...
i thought my 40kv probe was burned... it kind of don't show 40Mohm as before.(it never did i confused).. ... the new differential probe has 40Moms between inputs and 20Mohm between inputs and ground.. this 40kv probe has 1000Mohm resistance... its output impedance is 1,1Mohm that when in parallel with the resistance of a 10Mohm input dmm makes exact 1Mohm... so the total resistance is 1GOhm
the only reading of resistance i have at the 1000:1 40kv probe is 1,1Mohm across the leads that should go to the multimeter..
i was planing to use this probe to monitor the voltage potential of the cell while the other probe would be connected across the cell to get the potential diference.
the nicer thing about it is that i just discovered i can connect it to a oscilloscope too but the division would be 2000 instead of 1000...
the problem is it would need some compensation to get the right wave form.. my model is the tt hvp40 from testec like this on farnel anyone has ideas of how to make a compensation ckt for it?
thats because the oscilloscope has 1Mohm input impedance and together with the 1,1Mohm output impedance of the probe makes the impedance around 580k so it won't be 1000 to 1 anymore... im thinking to make a bnc connector with a trimpot to fine adjust the probe voltage reading...
