Hi
I have a current transformer with burden resistor fixed to it and it is connected to differential amplifier circuit then connects to ADC of a microcontroller. Is it possible to measure the resistance of the burden resistor using the connected ADC? I have different current transformer with different burden resistor, I want to know which current transformer is connected to the circuit.
CT is to measure 50Hz AC current.
Since the CT is ac current source and burden resistor is a load resistor connected to it, how can I measure the source impedance of the CT?
Thanks.
