This discussion focuses on measuring energy levels of transients in electrical circuits, emphasizing the importance of source impedance and load characteristics. Participants suggest that no single piece of equipment can universally measure arbitrary transients; instead, using an oscilloscope to capture current and voltage waveforms is recommended. For accurate measurements, a magnetic current probe accessory is advised to avoid series connections. The source impedance ranges from 50 to 200 ohms, while the load varies between 0.5 and 1.5 ohms, affecting measurement accuracy.
PREREQUISITESElectrical engineers, circuit designers, and technicians involved in transient analysis and energy measurement in electrical circuits will benefit from this discussion.
es1 said:Depends a lot on the source impedance of the transient and what load it is going into. I don't think there is a single piece of equipment that can just do it or any arbitrary transient.
Unless this is some kind of industrial application transient (like Ws of power or something) I would just try to get the current and voltage waveforms on a scope and determine it directly.
I suppose this would work even for many amps delivered to the load too but you would likely want to use some kind of magnetic current probe accessory on the scope to keep from having to use something in series with the current.
