摘要
电压互感器易受到外界电磁干扰而影响测量精度,提出用小波变换的方法对互感器测量误差进行校正,着重分析小波变换在信号去噪中的应用,仿真和实验研究结果证明所提方法的有效性。
Voltage transformers are susceptible to the environment electromagnetic disturbance which impact their measurement accuracy. This paper presents a method based on wavelet transform to calibrate the measurement error of voltage transformers and analyses the application of wavelet transform to signal denoising. Simulation results show that the method is effective.
