Profile: Lilco Ltd provides broadband terminated current transformers. Our current transformer measures the short circuit output current of a pulse generator. The use of current transformer is to measure current in electric circuits is that the measurement circuit can be electrically isolated from the circuit under test. The matching resistor is used to match the output impedance to 50 ohms. The output resistance of the broadband internally-terminated instruments is matched at the time of manufacture. Our broadband terminated current transformer can accurately measure current waveforms without electrical contact to the circuit under test.
