1产品概述
故障录波仪主要用于记录和分析电力系统发生故障前后相关电参数的变化过程及开关动作行为的装置的设备，利用其在故障前后一段时间记录的系统运行数据可以很方便地查出故障原因，也可作为故障反演时作为特征波形的重要数据来源。
传统的故障录波仪以单装置最多可采集96个模拟量、192个开关量的集中式故障录波装置为主，且受数据传输速率与存储容量的限制，不能对电信号或开关信号进行高采样率下的长时间录波，这给事后的故障分析带来很大的麻烦，同时集中式录波也不便于用于故障反演。
FTT131分布式高频录波仪就是为了解决上述问题而研制的。
FTT131分布式高频录波仪具有以下特点：
➢全通道高采样率采集与录波
➢高精度采集与录波
➢长时间连续录波
➢故障波形持续时间可编辑
➢支持多种录波触发方式
➢高精度IRIG-B对时
➢便携式设计，体积小，重量轻
