Definition
A current sensor converts the current flowing through a conductor into an easily measurable output voltage that is proportional to the current. Among the many different types of current sensors, each is suitable for a specific current range and environmental conditions.
Most commonly used are current sense resistors, which directly convert current linearly to a voltage. However, current sensing resistors must be inserted into the circuit to be measured and will cause a voltage drop there. In high-voltage applications, the possibly dangerously high potential of the measuring voltage with respect to ground can also be problematic.
In comparison, high-frequency current transformers (HFCTs) allow accurate, non-contact, non-destructive and potential-free measurement of currents in cables or other conductive materials. HFCTs are designed to provide measurements of either a single or a repetitive bipolar or unipolar current pulse. With the conductor of interest placed inside its solid toroid core, a high frequency current transformer will measure DC current ranges of e.g. 200 to 20,000 A or AC current ranges of e.g. 2 to 70 A.
Current Transformers come with various opening sizes (e.g. from 1/4 inch to 2 inches for our range of transformers). The output signal is an accurate voltage waveform representation of the measured current, which can be analyzed on an oscilloscope, RF power meter, spectrum analyzer or custom interface circuitry. It also works for the continuous wave. Depending on the maximum current specification, the sensor’s voltage output may range from 0.025 V/A to 5.0 V/A.
