To fully visualize the overvoltage surge losses caused by the absence of a surge protection device, it is necessary to include equipment replacement\/repair costs, data recovery costs, and downtime losses. due to failures and lost opportunity costs. In addition, human life can also be put in danger if the safety systems fail to function due to overvoltage pulses.<\/span><\/p>\n<p><span style=\"font-size: medium; color: #000000;\">According to the Insurance Information Institute, NY, (NY Press Release, August 11, 1989): Lightning surges and other overvoltage surges can cause damage to property, electrical-electronic, and telecommunications equipment. is estimated at more than $1.2 billion per year in the United States alone. This amount represents approximately 5% of insurance costs across the United States.<\/span><\/p>\n<p><span style=\"font-size: medium; color: #000000;\">According to Holle et al., Journal of Applied Met, Vol 35, No.8, August 1996: The premium for damage due to surge surges and other overvoltage surges is $332 million annually in the United States, but many organizations still don't cover this type of property damage. On average, only 1 in 57 lightning strikes are insured in the United States.<\/span><\/p>\n<p><span style=\"font-size: medium; color: #000000;\">In Vietnam, according to 2001 statistics, there were 400 incidents in the electricity industry, 50% of which were caused by lightning (Tien Phong Newspaper, 08\/08\/02). As for the Post and Telecommunications industries, there are 53 incidents caused by lightning (27.13% of telecommunications incidents), causing a loss of 4.119 billion VND, and the total time of loss of communication due to lightning is 716 hours (lightning protection for telecommunications networks.

The economic benefits of these devices have been widely recognized. Microcomputers are very common, and microprocessor-based programmable controllers (PLCs) are used in most manufacturing equipment. Microprocessors can also be found built-in in many industrial machines, security and fire alarms, timekeeping equipment, inventory tools, etc.<\/span><\/p>\n<p><span style=\"font-size: medium; color: #000000;\">Judging by the wide range of sources of overvoltage surges (due to lightning propagating, generated in equipment) and the potential for large losses caused by power interruptions, the initial installation costs of protective devices Overvoltage impulses, especially surge protection devices, are reasonable for any vehicle or device. The cost of surge arresters is usually approximately 10% of the economic risk cost of the equipment to be protected.<\/span><\/p>\n<p><span style=\"font-size: medium; color: #000000;\">For effective protection, ERICO's six-point comprehensive lightning protection solution should be followed. Points 5 and 6 in this solution meet the needs of surge protection for power lines and surge protection for signal lines. At point 5, the first layer of protection is the primary surge arrester at the input, followed by the secondary surge protection device at the distribution switchboard or at other necessary points.<\/span><\/p>\n<div align=\"center\"><span style=\"color: #000000;\"><img decoding=\"async\" class=\"alignnone wp-image-3769\" src=\"https:\/\/toancau.vn\/wp-content\/uploads\/2021\/08\/giai-phap-chong-set-6-diem-4-300x224.png\" alt=\"\" width=\"396\" height=\"296\" srcset=\"https:\/\/toancau.vn\/wp-content\/uploads\/2021\/08\/giai-phap-chong-set-6-diem-4-300x224.png 300w, https:\/\/toancau.vn\/wp-content\/uploads\/2021\/08\/giai-phap-chong-set-6-diem-4-16x12.png 16w, https:\/\/toancau.vn\/wp-content\/uploads\/2021\/08\/giai-phap-chong-set-6-diem-4.png 578w\" sizes=\"(max-width: 396px) 100vw, 396px\" \/><\/span><\/div>\n<p align=\"center\"><span style=\"font-size: medium; color: #000000;\">A 6-point lightning protection solution<\/span><\/p>\n<p style=\"text-align: right;\" align=\"center\"><span style=\"color: #000000;\">Ngu\u1ed3n: WWW.ERICO.COM<\/span><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>N\u1ed9i dung b&agrave;i vi\u1ebft1 T\u1ea1i sao c\u1ea7n l\u1eafp \u0111\u1eb7t thi\u1ebft b\u1ecb\u00a0ch\u1ed1ng s\u00e9t lan truy\u1ec1n?1.1 I.
