We would like to introduce examples of lightning damage countermeasures for electrical equipment in universities (research facilities). Universities (research facilities) have many expensive devices installed, such as precision instruments, research equipment, and supercomputers. In addition to the damage to the equipment itself caused by lightning strikes, the interruption of experiments, loss of observational data, and disappearance of research data due to lightning damage can result in even greater losses. Our company has supplied a large number of lightning protectors, primarily for high-capacity power supplies, to a science and engineering university located in a mountainous area where lightning strikes are frequent and concerns about lightning damage to various equipment were raised. 【Case Overview】 ■ Issues - Attention is needed to ground lightning surges that can wrap around from lightning strikes to lightning rods and other devices. - In cases where there are multiple buildings, the ground potential difference between buildings can cause lightning surges to propagate not only to the building that was struck but also to nearby buildings. ■ Countermeasures: We propose VAJ-type lightning protectors for high-capacity power supplies at the main power distribution panel of floors with critical loads, and VNJ-type and VTJ-type lightning protectors for communication lines and signal lines depending on the equipment situation. *For more details, please download the PDF or feel free to contact us.
