MEGGER AVO电力电缆故障检测与诊断仪器仪表总揽

MTDR1

电缆故障单相时域反射定位仪

一、产品特点

• 多重故障定位法
• 自动量程设置，自动故障距离显示模式
• 单相、双通道发送-接收机
• 与市面上多种 强力脉冲发生器/滤波器 相兼容

二、产品简介

       MTDR1利用脉波回声(pulse echo)、弧反射（arc reflection）、弧反射差(differential arc reflection) 或瞬态分析的方法(电压及电流)来做缆线故障的先期定位。本仪器可以独立使用或与Megger PFL系列产品配合使用。

      使用MTDR做故障预定位，可以减少先期定位点的数目，从而大幅地减少故障定位的时间。

      MTDR是快速找出电力电缆障的主要工具。它可以减少使用强力脉冲来查找电缆故障所花费时间并减少对电缆的损坏。

MTDR1
Single-phase Time Domain Reflectometer

• Multiple fault locating methods
• Auto-ranging and auto-fault distance modes
• Single-phase, two-channel transceiver
• Compatible with various surge generators/filters combo on the market

The MTDR1 is used for prelocating cable faults utilizing methods such as pulse echo, arc reflection, differential arc reflection or transient analysis, both voltage and current. The unit is available as a stand-alone, or can be integrated into the Megger PFL Auto series line of products.

Using the MTDR for prelocation significantly decreases fault locate times by reducing the number of surges required to prelocate, reducing the number of surges required to pinpoint.

The MTDR is your prime tool in the battle to quickly find your faults. It eliminates the time consuming and damaging process of repeatedly surging your cable in an effort to find faults
