IEC TR 63396:2021（E）记录了电力电容器单元的声压级测量方法，通过该方法确定电力电容器单元的声功率级。 该方法适用于额定电压为1 kV及以上、频率为50 Hz或60 Hz的交流电力系统的并联电容器单元和交流滤波电容器单元。 该方法也适用于直流滤波电容器单元。 关于电力电容器单元的其他测量可以参考该方法来实现。

IEC TR 63396:2021(E) documents a method for the sound pressure level measurement on power capacitor units, by which the sound power level of power capacitor units is determined.
This method is applicable to shunt capacitor units and AC filter capacitor units for AC power systems with a nominal voltage of 1 kV and above and a frequency of 50 Hz or 60 Hz.
This method also applies to the DC filter capacitor units.
Other measurements on power capacitor units can be implemented with reference to this method.
