  • Micromodular hot and cold aisle design

    Micromodular hot and cold aisle design

    Intelligent hot/cold aisle containment with fully enclosed design, combined with dual-source air conditioning and anti-condensation systems to effectively handle high-temperature, high-density scenarios. While advanced cooling systems like chilled water plants and CRAH units play a major role, one of the most effective strategies is much simpler: controlling how air moves through the data hall. Hot aisle and cold aisle containment are foundational concepts in data center design. This method raises the temperature of the air returning to a Computer Room Air Con itioner (CRAC) unit, which allows the unit to operate more eficiently.


  • 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.

  • Design Principles of Optical Cable Networks

    Design Principles of Optical Cable Networks

    Fibre optic network design is the structured engineering process of planning how optical fiber infrastructure connects buildings, campuses, cities, and regions. It includes determining the type of communication system(s) which will be carried over the network, the geographic layout (premises, campus, outside plant. Designing a fiber optic network is like planning a city's road system, it needs to be efficient, reliable, and built to handle both current and future traffic. Whether you're new. Operators define the network's topology, equipment needs, communication system, and set of services that will be made available to users. Planning and design involves coordinating everyone engaged in any way to consider all requirements while staying on the same page.

  • 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.
