A new on-line measurement system of dielectric loss angle (δ) with FPGA for high voltage capacitive apparatus is presented in this paper. By using double polarity zero crossing point comparing method for measuring phase difference, system frequency measurement and measurement error adaptive corrected with FPGA is adopted. Tests results show that the measuring system based on FPGA is with higher precision, stabilit...
