摘要

分析了传统的谐波分析法在介损测量中存在的问题

研究了两种改进的测量介损的算法——加窗插值FFT法和基于小波的介损测量方法

对比了各种方法的优缺点。现场实际测量表明

两种方法均能有效提高介损测量的准确性。

Abstract

This paper analyzes the problem existing in the conventional harmonic analysis method

investigates two digital arithmetic-hanning-windowed interpolated FFT and wavelet analysis method for dielectric loss measurements

and contrastes their advantages and disadvantages.The on-site tests indicate that both methods have good accuracy in measuring dielectric loss.
