Abstract :
The signal sampling system of the on-line high voltage insulation diagnosis device mainly made up of two parts, current sensor and waveform sampling system, is presented in this paper. The design methods for the current sensor and waveform sampling system are put forward. The structure and shielding of the current sensor are also discussed. The laboratory testing results are given. Finally the relationship between sampling rate of the data sampling system and accuracy of the device is analyzed
