| 中文摘要: |
| 电流互感器是电力系统中不可或缺的电气设备，其性能直接影响继电保护、电能计量和远程监控能否稳定可靠 运行。本文通过阐述电流互感器剩磁产生的原因，从理论上分析了剩磁对测量用电流互感器运行的影响。最后提出了 减小或消除电流互感器剩磁的可行措施。 |
| 英文摘要: |
| The current transformer is widely used in power system, and its stable and reliable performance directly arects relay protection, power metering and remote monitoring. In this paper, the reason of residual magnetic field of current transformer is explained, and the theoretical analysis of residual magnetic e?ect on current transformer for measurement is provided. Finally, the feasible measures to reduce or elIminate the remanence of current transformers are proposed. |
