This paper introduces a continuous wavelettransformation for detecting the disturbed partial discharge pulses in HV transformer.
采用了子波函数对含强载波干扰的局部放电信号进行连续子波变换。

Calculates the setting range of each parameter in theory, and proves the method of wavelettransformation has higher frequency resolution than the method of FFT.
从理论上计算各个参数的设置范围，并且证明小波变换方法比FFT方法有较高的频率分辨率。

The result shows that the wavelettransformation would be used to constrain the static shift in MT, which is effective and potential method of static correction.
