#K40LPS
Newest lightning strike:
I wanted to test what happens with a fully open circuit. Notice the acrylic barrier in the gap.
This may be what was wrong with this supply?
Well that was interesting.
What was the end of the HV lead doing at that time? Any corona?
And how about the mA-meter. (Both were just out of frame.)
Just another reason to be sure everyone’s K40’s have solid grounding. (As shipped from the factory, they are shit.)
To aid in your experiments, @donkjr , you may want to put a parallel resistor across you mA meter. That way, instead of 0-30mA you could change the range to 0-300ma or even 0-3000mA. (The resistor math is an exercise left to the student.)
@Nate_Caine The HV lead was just connected to the black plastic post and it had no corona. The meter reads 5-10 ma. Yes I could configure a multi-range amp meter …
Grounding is critical and this amount of energy dictates an interlock on the laser compartment door …
Whoa, would not have expected that to happen. Very interesting. Thanks for your work Don.
