How to size shunt resistor
WebWhat size shunt resistor should be used? The size of the shunt resister depends on the maximum current rating. It is calculated by the voltage drop at the maximum current rating. Let say a shunt resistor is designed for maximum current 100 A and voltage drop 50 mV. Typically, the voltage drop at maximum current is 50 mV, 75 mV, or 100 mV. WebMar 10, 2024 · The better way to do the current sensing is to use a current transformer - this will be safer and provide isolation. Current transformers might have a primary with just one turn and a secondary with 1000 turns - this will give a ratio of 1:1000.
