Inductive Current Sensing
Complex Hacks

How do you detect the actual current from your 22,500uF, 450VDC capacitor bank when you pulse discharge it? Well Norman from Procrastinatus shows us his method. Inductive Current Sensing is done using a Rogowski coil which is wrapped around the high current output of the capacitor bank. A DSO is used to capture the data so the short event can be analyzed. Norman entered this into the Tektronix scope competition
