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

IMPULSE GENERATOR
15-kV Portable Impulse Generator

  • 15-kV Portable Model
  • Dual-Voltage Model
  • Heavy-Duty Model

Impulse Generators are designed to locate faults in power cable by the high voltage impulse method, in which a high-voltage impulse is transmitted down the cable to cause the fault to arc. The arcing fault is then pinpointed using an appropriate impulse detector.

Impulse Generators may also be used to perform voltage versus time acceptance tests, or to burn faults that fail to break down under impulse to reduce their resistance. Megger offers four models to meet every application.

ELECTROMAGNETIC IMPULSE DETECTOR
Electromagnetic Impulse Detector

  • Indicates direction of fault
  • Works under all weather conditions
  • Survives rough handling and transport
  • Converts to voltage gradient tester with optional earth frame
  • Long-lasting 9-volt battery

The Electromagnetic Impulse Detector has been designed to localize faults on buried cable by detecting the magnitude and polarity of current established on a cable during surging with a surge generator.
The instrument is composed of an amplifier module, sheath coil, and carrying case. It is typically used on network systems to isolate a fault between manholes. An optional earth frame and surface coil are available.
The Electromagnetic Impulse Detector can be used with Megger PFL Systems or with surge generators of other manufacturers.

Arc Reflection Filter
Standard Arc Reflection Filter and Heavy-Duty Arc Reflection Filter (detachable)

  • Choice of standard and heavy-duty models
  • Delivers highest energy levels to the fault, improving fault locating capability
  • Designed for safe, continuous operation with appropriate companion impulse generators
  • Designed for minimum trace distortion on companion time domain reflectometers

With Arc Reflection Filters, cable faults can be located on power cables rated at up to 35 kV. Relatively small systems, such as most direct buried underground residential distribution (URD) systems, are easily satisfied with the standard filter. Larger systems, including especially long direct buried distribution cable and especially complex circuits using lead-covered cable, require much more energy (such as is made possible using the heavy-duty filter).

MPP1000 电缆故障探测器

一、产品特点

  • 与PFL系列设备结合实用，确定电缆的故障点和走向
  • 工作于任何气候条件
  • 探测15m距离内的故障
  • 声频范围125－1000HZ，增益自动调节
  • 通过脉冲指示提醒操作者浪涌周期
  • 通过调节音频消除干扰
  • 电池寿命超过200小时
  • 单、双两种测试组合形式

二、产品简介

      MPP1000故障探测仪通过检测故障点的电磁及声音信号对电缆的故障进行精确定位。MPP1000可与AVO公司其它生产厂家生产的脉冲发生器合用，MPP1000可作为AVO公司生产的电缆故障测试PFL-4000、PFL-5000及PFL-6000系列的附助作用。

      仪器有单、双两种组合型式，单测试仪通过测试电磁与声音信号的延时进行判断距离故障点的距离，通过双测试仪可测试距离和方向。

三、产品应用
      MPP1000用于对铠甲直埋的电缆进行故障定位。当电缆被发脉冲时，通过探测声音与电磁信号之间的延时进行精确定位。当脉冲发生器向电缆发送大能量脉冲时，电缆发生弧光，并随之发出声音，由于电缆一般情况下埋在地下0.9M左右，因此发出的声音如果无放大器不能够都被听到。有时单个放大器不足以判别故障点，当用双探测器时能够迅速地找到故障点的方向和距离。
      仪器通过测试声音与电磁两种信号的时差而进行定位，在接收器中可显示声音信号的强度及两种信号的时差。当测试仪靠近故障点时，声音信号加强，而两信号的时差降低，这两个数值为用户提供一个大约的距离。当再用一个探测器时，接收器将显示故障点的方向。

四、产品特征

1. 通过测试电磁脉冲和声音信号，可快速有效地判断故障点的方向及距离。
2. 重量轻，防水外壳，操作者可工作在任何气候条件。
3. 可测试15m以内距离的故障。
4. 听筒能很好的消除周围的噪音
5. 同时使用声频结合能消除环境干扰

MPP1000
Megger Pinpointer

  • Cable fault distance and direction via single or dual detection configuration
  • Rugged, compact weather resistant housing
  • Ambient noise reduction headphones
  • Easy, trouble-free probe connection with a detachable cable system
  • Fault detection up to 50 ft (15 m approx) away and extended battery life
  • Ballistic pulse scale provides thump magnitude and surge period
  • Background interference elimination via selectable acoustic frequency band  

Specifically designed for service, industrial and power utility companies, the MPP1000 pinpoints faults in shielded and direct buried primary cables via a single or dual probe. A single probe version can be easily upgraded at any time by purchasing a second probe. The MPP1000 stand-alone unit (without probes) measures electromagnetic surge and supplies the amplitude of that surge which aids in finding the fault. Overall, the versions can successfully detect both the electromagnetic and acoustic pulses emitted from an arcing fault when it is surged. They can also be used with any Megger PFL Power Cable Fault Locating system/surge generator or other supplier.
