John,

This actually looks like it makes sense. I plotted your results (see attached). Can you document this in greater detail including the test setup etc. and include it in your MPO. Are you ready to do the ring testing and impulse testing? I would like for you to move ahead with the ground wrapping asap.

Thanks,

Mike

Mike.

Here are the testing results on the actual coil ;

Voltage Across Coil Leads Voltage on One Turn Coil Current Turn To Turn Short

with 750ohm betwn leads of Growler Primary (amprobe around 12 turns) Resistance

750V 67.4 1.158 open(no short)

749V 67.4 1.753 10 ohms

752V 67.4 1.285 50 ohms

751V 67.4 1.213 100 ohms

751V 67.4 1.186 200 ohms

750V 67.4 1.179 250 ohms

749V 67.4 1.176 300 ohms

750V 67.4 1.171 350 ohms

750V 67.4 1.167 400 ohms

750V 67.4 1.163 500 ohms

The test results were not very sensitive to the location of the coil in the Growler but we fixtured it in place anyway. The same is true of the location of the amprobe around the coil.

Here are the test results of the 12 turns of lead wire wrapped around the Growler that we gave you over the phone a few days ago;

Voltage Across Leads Voltage on One Turn Coil Current Turn To Turn Short

with 750ohm betwn leads of Growler Primary (amprobe around 12 turns) Resistance

750V 68.9 1.062 open(no short)

752V 68.9 1.654 10 ohms

752V 68.9 1.189 50 ohms

752V 68.9 1.122 100 ohms

751V 68.9 1.081 200 ohms

751V 68.9 1.072 250 ohms

751V 68.9 1.068 300 ohms

752V 68.9 1.066 350 ohms

751V 68.9 1.058 400 ohms

751V 68.9 1.057 500 ohms
