  • Relay Protection Virtual Platform Design

    Relay Protection Virtual Platform Design

    This whitepaper, co-authored by Intel and Kalkitech describes the virtual protection relay (VPR) concept – an architecture where software-defined and virtualized platforms are deployed to host the critical circuit protection functions for an advanced and agile grid. We assert that this use of. Edge Analytics the availability of IEC-61850-3 certified servers built for substations and VMware vSphere supporting latency-sensitive workloads in the substation. Modern substations require standardized, flexible, scalable, and secure systems to build a data-driven power grid to improve the local. A Virtual Protection Relay is a protection system implemented entirely in software instead of a physical relay box. We outline virtualizati n technology and the networking aspects using performance benchmarks laid by IEC 61850 standards. Protective relays have evolved steadily over time. Early power systems relied on electromechanical relays, which were later. As the energy sector is confronted with the high penetration of renewable energy sources, one of the key aspects of the grid controls which are put under stress is the grid protection sub-system.

  • Why do optical cables need protective grounding

    Why do optical cables need protective grounding

    Many fiber optic cables include metallic components — such as steel armoring, aluminum moisture barriers, copper strength members, or metallic messenger wires — that absolutely must be grounded to prevent electric shock, equipment damage, and fire hazards. While nonarmored fiber optic cables don't require grounding due to their nonconductive properties, grounding is crucial when using armored fiber optic cables. These cables include metallic components that can carry electrical currents, presenting potential hazards such as electrical shock or fire. Fiber optic cable transmits data as light through glass or plastic strands, which means the fiber core itself carries no electrical current and requires no grounding. The critical distinction lies in. This Applications Engineering Note (AE Note) discusses conventional bonding and grounding practices for conductive fiber optic cable and hardware installations within the scope of the National Electrical Code (NEC). In copper cables, bad things happen if we don't do it. • The cables become susceptible to power influence and other external noise issues.

  • Standard for protective grounding strips in distribution boxes

    Standard for protective grounding strips in distribution boxes

    26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Today, we're diving deep into the world of distribution box grounding, breaking down the standards, and shining a light on those sneaky mistakes that even experienced electricians sometimes make. Whether you're a seasoned pro or just starting out, this comprehensive guide will give you practical. In industrial and civil circuit wiring, the stainless steel monitor enclosure device serves as the physical casing for various switches and control components. Each DISTRIBUTION BOX and controller must be grounded. Protective grounds must be installed so all phases of lines or cable are visibly and effectively bonded together in a multi-phase. Abstract: Discussed in this recommended practice is the system grounding of industrial and commercial power systems. The recommended practices in this document are intended to provide explanations of how electrical systems operate. It can also be an aid to all engineers responsible for the.
