5%,谐波电流以 5, 7 为主,5 次达到 320A，7 次 160A。 (2)2007-10-24 13:57 至 14:17 电容柜投运时 2#主变 0.4KV 谐波 谐波电压总畸变率达到 8.8%左右，超出国标值 5%,谐波电流以 5, 7 为主,5 次达到 387A，7 次 170A。 (3)2007-10-24 14:49 至 15:17 电容柜投运时 3#主变 0.4KV 谐波 谐波电压总畸变率达到 5%左右，A,B 相超出国标值 5%,谐波电流以 5, 7 为 主,5 次达到 150A，7 次 40A。 1,2主变负载最大电流可以达到 2400A，故到时 0.4KV 母线谐波情况比目 前还要严重；3主变目前负荷比较小，公司已拟新增生产车间，由 3主变 供电，到时 3主变电流增大，如果生产线含有直流调速电机等设备，谐波电 流含量势必会增大。 从低压侧的谐波测试数据表明，三台主变在投入电容的情况下，0.4KV 侧谐 波电压，电流达不到国家标准值。 8 监控时间：2007-10-24 13:20到：2007-10-24 13:50电压等级：0.22 KVPT:1CT:400基准短路容量： 10 MVA用户协议容量 1.25 MVA最小短路容量： 20.7999992 MVA供电设备容量： 1.25 MVAFLUKE
