The CD current sensing series is designed for monitoring and detecting leakage current on railway applications (fixed installations and onboard).
CD sensors’ high sensitivity allow for the measurement of a differential current that is only 0.1 % of the main current flowing in each primary conductor. For example, a differential current of 1 A can be measured with a main current of 1000 A, or 0.1 A with a main current of 100A. The measurement accuracy is about 5 to 10 % within the specified operating temperature range.
CD current sensors are based on the closed loop Fluxgate technology (C type).
CD current sensors are commonly used in traction applications:
