Abstract Burning out of capacitance compensation cabinet and trip failure of main breaker of low-voltage cabinet have happened for several times in the substation of a data center which has been put into operation. According to the field investigation，it is believed that the electric failures may be caused from excessive UPS configuration for the terminal computer，and harmonic pollution caused from using of a large number of LED lights.　Effect of application of active power filter to the data center is introduced on the basis of field measurement of the harmonic data before and after setting of active power filter.

摘 要 某已投入运行的数据中心变电所多次发生电容补偿柜烧坏及低压柜主断路器跳闸故障，作者现场考察认为故障可能是末端计算机所带UPS过多，以及大量使用LED灯导致的谐波污染而引起的电气故障。通过实测设置有源电力滤波器前后的谐波数据，说明有源电力滤波器在数据中心的应用效果。
