  • How to connect access switches in series

    How to connect access switches in series

    Daisy chain topology, as suggested by its name, connects each switch in series to the next, akin to the petals of a daisy. This configuration can be linear (where the switches at both ends are not connected) or circular (where the switches at both ends are connected). But how can we connect network switches together? This article will explore three common connection methods: switch cascading, switch stacking, and switch clustering, and will help you determine the best approach based on network size, performance requirements, and management needs. That is because they offer specific benefits that many modern network designers find. We need to connect 2 switches together and have 2 options for them:- 1. Use access port on both sides 2. Cascading is the traditional method of connecting multiple Ethernet switches.

  • How to handle second harmonics in relay protection

    How to handle second harmonics in relay protection

    Set EHBL2P to Y to enable second harmonic blocking. Use the NOT HBL2T relay word bit in the 67P1TC torque equation to prevent the instantaneous high set phase overcurrent element from operating during inrush. Among these, the second (100/120Hz) and fifth (250/300Hz) harmonics are particularly problematic, necessitating their blockage in protection relays to ensure system reliability. In this extensive guide, we explore harmonic detection and mitigation strategies, delve into their technical. Harmonic restraining in differential protection is a technique used in transformer protection to prevent false tripping during inrush or over-fluxing conditions by detecting and blocking specific harmonic currents—mainly the 2nd and 5th harmonics —commonly present during non-fault events. Figure 1a is the oscillography captured. Protective relays exploit this characteristic through harmonic restraint logic: Typical 2nd harmonic restraint thresholds range from 15% to 25% of the fundamental.

  • How many times can an optical fiber splitter split the fiber

    How many times can an optical fiber splitter split the fiber

    The splitting ratio is determined by the input and output of the fiber optic splitter. The maximum split ratio of the FBT splitter is as high as 1:32, which means that one or two inputs can be divided into outputs of up to 32 optical fibers. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network Terminals (ONTs) at users' homes, splitters eliminate the need for dedicated fibers to each residence—slashing infrastructure costs while scaling network reach. The optical network system uses an optical signal coupled to the branch distribution. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. Fiber splitters are passive devices that divide one optical input signal into multiple outputs. In fact, in simple terms, it is to distribute 1000Mbps bandwidth to four families equally, and each family can use a network with 250Mbps bandwidth.
