One-dimensional signals characterizing the insulation state of cable terminals

The high-frequency current transducer is capable of capturing HFCT signals in the 3 MHz to 30 MHz bandwidth with an integrating resistor value of 50 Ω. The high-frequency current transducers have a sampling ratio of 8 mV:1 mA and a detection sensitivity of up to 0.5 pC. The phase synchronizer is employed to ensure signal phase synchronization between the detection equipment and the vehicle cable terminals to accurately characterize the HFCT signal. It is essential to align the shielding environment and the surrounding electrical equipment to perform the experiment in a halo-free environment where the background noise of the test system is less than 3 mV. The experiment is performed by snapping the HFCT sensor to the cable ground wire and setting the acquisition frequency to 100 MHz.Sample the original data 10,000 times using peak hold sampling.
