Luan Guo · Electrical Equipment · 2005
In this paper, considering the characteristic and requirements of the tg δ measurement based on the harmonic analysis method, two parameters, i.e. sampling frequency and sampling accuracy are the most important ones for the sampling system, and analyzed in frequency domain deeply. The way that the parameters affect on the sampling system is concluded. Based on it, the principle and the method to determine the optimal sampling parameters are presented. As a result, theoretic basis is provided for devising sampling system effectively.
