Abstract

A new measuring system of dielectric loss factor (tandelta) with TMS320F2812 DSP for high voltage capacitive apparatus is presented in this paper. By using harmonic analysis method for measuring phase difference, the quasi-synchronous algorithm and measurement error adaptive corrected with DSP is adopted. Test results show that the measuring system based on DSP has higher precision, stability and anti-interference reliability.
