Current-sense transformers create an alternating current in the secondary winding that Is proportional to the current passing through the pnmary winding. The current in the secondary is converted by a burden’ resistor - or terminating resistor (RT) - to a low voltage that can easily be measured in circuit.
A typical off-the-shelf current sense transformer has a 1-turn primary and a high-turns secondary. Alternating current passing through the primary winding creates a magnetic field that Is coupled to the secondary. This field develops a voltage across the secondary and RT. With a 1-turn primary, the voltage drop (V) across R1 is proportional to the current through the primary (1.) according to this equation: V= (l X RT)/ N. where N is the number of secondary winding turns. Therefore, selection of the terminating resistance is important In setting the correct maximum output voltage corresponding to the maximum expected primary current.
