  • Grounding wire of cable tray support

    Grounding wire of cable tray support

    If a wire mesh cable tray is supporting cable with a built-in equipment grounding conductor or control or signal cables, then the tray should have a low impedance path to a non-system ground to reduce noise and remove induced or stray currents. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. The flexibility and scalability of cable trays make them an ideal choice for environments where cable density and organization can. The Cable Tray Grounding Wire ensures everything runs safely and smoothly. It helps protect equipment from electrical faults, preventing fires and shocks. But, how do you make sure your grounding system works as it should? Let's dive in. You should consider it as a series of instructions that make the buildings resistant to. The intent of this article is to review grounding practices for cable tray wiring systems.

  • Application of fiber optic cable for downhole temperature measurement in Papua New Guinea

    Application of fiber optic cable for downhole temperature measurement in Papua New Guinea

    Here we outline some new technologies in this context within case studies from different research projects including permanent installation of fiber-optic sensor cables behind casing, monitoring of high-temperature wells, a hybrid wireline logging system, and seismic. Here we outline some new technologies in this context within case studies from different research projects including permanent installation of fiber-optic sensor cables behind casing, monitoring of high-temperature wells, a hybrid wireline logging system, and seismic. Conventional measurement systems: usually based on electronic sensors. Limitations: temperature, complexity, cost. Raman: inelastic scattering, interaction with molecular vibration and rotation. By embedding fiber optic cables within wellbores, operators gain real-time, distributed data over the entire depth of the well. Techniques like distributed acoustic sensing (DAS), distributed temperature sensing (DTS), and distributed strain sensing (DSS) unlock a 3D, time-lapse view of well. Fiber optic instrumentation designed for downhole monitoring and mining projects.
