摘要
本文从408FDU的组成及其主要功能出发,以畸变、对地电阻故障为例对畸变测试电路和对地电阻的校验原理进行了分析,并针对408FDU的常见故障提出了解决问题的思路和有效方法。
Based on the composition and main function of 408 FDU, taking the failure examples of the distortion and resist- ance to ground, this article analyzed the working principle of distortion testing circuit and the calibration of returning to ground resistance. The article also put forward some effective methods for 408FDU repairing work.
