基于LTC1068光纤电流互感器的二次侧信号处理

摘要

The basic principle of the fiber-optic current transducer based on the Faraday effect is introduced. The design of optical current transformer secondary-side signal processing using switched-capacitor filter LTC1068 is presented in detail. Finally the test results are given. Test results show that using LTC1068 to process secondary- side signals is practical and effective, and fully meets the measurement requirements.%介绍了基于法拉第效应的光纤电流互感器的基本原理,并利用开关电容滤波器LTC1068进行光纤电流互感器二次侧信号处理的设计方法。给出的测试结果表明,利用LTC1068进行二次侧信号的处理方法实用有效,完全满足测量要求。
