Abstract The second output signal of Hall high current sensor will be attenuated in its frequency characteristics. The frequency response tests of model LT1005-S 1000A high current sensor 50Hz~1kHz and LT2000-T 2000A high current sensor 50~400Hz were designed . The output performance of Hall high current sensor that the frequency characteristics of attenuation caused by the increase of the original current amplitude and frequency was objectively verified by data analysis and processing,the research can provide some data reference for the measurement calibration and practical application of Hall current sensor.
