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。
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.
