I am trying to measure the current on an Meibach Welder at our plant. The welder is used to weld stainless steel coils of max width 1500mm and gauge 2mm. The welder operates intermittently and current values vary across a wide range. I do not know what the exact current values are and what the...
I am currently developing a test circuit to output a lightning current wave with a peak of 10kA. My problem is that in order to get the required characteristics of the wave ie. rise and fall times, I need a 0.3ohm resistor. I am not sure what type of material to use that would sustain a peak of...
