This paper de- signed a data-sampling and processing system with good performance of electrical insulation. Af- ter the I/F conversion of the collected signal on the side of high-voltage, the transformed signal will be transmitted to the side of low-voltage by the optical fiber communication system and then it will finish the data-sampling of the signal on the side of high-voltage after the F/D conversion of the received signal. Finally, the signal will be transmitted to DSP to make a subsequent processing. The test results show that the data-sampling system of the equipments on the side of high-voltage has a good linearity. It can attain the accuracy of 0.2%. Also it has superior anti-electromagnetic interference ability and high-voltage insulation ability.
