concordegas current transformer sanalysis

Current transformers are an efficient way to measure current. Since the burden resistor is reflected to the primary by 1/N 2, the resistance seen in the circuit being monitored can be very small. This allows a larger voltage to be created on the output with minimal effect on the circuit being measured.
