Results for tag: "High Voltage Surge Arresters"

In the context of hardware, High Voltage Surge Arresters are essential components used to protect electrical equipment from voltage spikes, typically caused by lightning or switching operations. These devices are used in electrical power systems, including transmission lines, substations, and distribution networks, to limit transient overvoltages and divert surge currents to the ground, thus shielding transformers, insulators, switchgear, and other hardware from damage. Surge arresters comprise a high-voltage terminal, a ground terminal, and a voltage-limiting component such as a varistor, which has a non-linear voltage-current characteristic. This allows the arrester to conduct significantly when a voltage spike occurs, clamping the voltage to a safe level, and then to return to a non-conducting state once the overvoltage passes. They are designed to withstand the physical and electrical stresses of the high voltage environment. Several manufacturers specialize in the production of high voltage surge arresters. Some notable companies in this market include ABB, Siemens AG, Eaton, General Electric, Hubbell Incorporated, Mitsubishi Electric Corporation, Schneider Electric, and Raycap. These companies offer a range of surge arresters in various ratings and designs to cater to the diverse needs of the electrical power industry. Show Less Read more
