Abstract

Analysis and Measurement Services (AMS) Corporation has been conducting two research projects focused on understanding cable aging and developing cable condition monitoring technologies for nuclear power plants. The goal of the first project is to develop a cable aging management program to correlate the aged condition of a cable with condition monitoring techniques that can identify and locate aging in the cable's polymer material as well as faults that may occur in the conductor. This project involves laboratory experiments using low and medium voltage cable types typically installed in nuclear power plants. The second project is focused on development of an integrated cable condition monitoring system for nuclear facilities. This system integrates a number of cable testing and cable condition monitoring techniques, such as time domain reflectometry (TDR), frequency domain reflectometry (FDR), inductance, capacitance, resistance (LCR), reverse TDR (RTDR), voltage, waveform acquisition, current-to-voltage (IV) for testing of nuclear instrumentation sensors, and insulation resistance (IR). The purpose of the project is to combine all proven technologies into one system to detect and pinpoint problems in cable circuits as well as cable insulation, shield, or jacket material.
核电站电缆状态监测
分析和测量服务公司(AMS)一直在进行两个研究项目,重点是了解核电站电缆老化和开发电缆状态监测技术。第一个项目的目标是开发一个电缆老化管理程序,将电缆的老化状况与状态监测技术联系起来,从而识别和定位电缆聚合物材料的老化以及导体中可能发生的故障。该项目涉及使用通常安装在核电站的低压和中压电缆类型进行实验室实验。第二个项目的重点是为核设施开发综合电缆状态监测系统。该系统集成了许多电缆测试和电缆状态监测技术,如时域反射(TDR)、频域反射(FDR)、电感、电容、电阻(LCR)、反向反射(RTDR)、电压、波形采集、用于核仪器传感器测试的电流-电压(IV)和绝缘电阻(IR)。该项目的目的是将所有成熟的技术结合到一个系统中,以检测和查明电缆电路以及电缆绝缘、屏蔽或护套材料中的问题。
