It has already been nearly 10 years since the Great East Japan Earthquake, which caused unprecedented damage. Since the earthquake, major earthquakes have occurred across the country, including the "Kumamoto Earthquake" and the "Hokkaido Eastern Iburi Earthquake in 2018." Furthermore, measures against the anticipated massive earthquakes, such as the Nankai Trough, where the source areas of the Tokai, Tonankai, and Nankai earthquakes are expected to be interconnected, are a common challenge for all companies and organizations. In this seminar, as we reach the 10-year milestone since the Great East Japan Earthquake, we will clearly introduce a wealth of information requested by many of you, ranging from basic knowledge of earthquake countermeasures to new strategies and case studies by facility type. By implementing the above, we will support the effective review of earthquake countermeasures and disaster prevention plans.

At Showaden, we have produced an "SPD Introduction Video" that clearly explains the features and handling methods of our new power supply and communication SPD, which has been available for viewing since January 19, 2021. Compared to traditional catalogs and still images, the content is more intuitive and easy to understand. We invite you to watch it.

At Showa Electric, we have renewed the "SPD Selection Support Site," which was launched in September 2020, to make it even more user-friendly, and it reopened on January 19, 2021. By simply checking items such as application and line type from over 100 types of SPDs available for power supply and communication, you can select the most suitable SPD. We invite you to make use of it.

The portable grounding electrode "Kappa-kun," jointly developed by Showden Co., Ltd. (4-3-8 Taihei, Sumida-ku, Tokyo, President Mitsuaki Ota) and Mirait Co., Ltd. (5-6-36 Toyosu, Koto-ku, Tokyo, President Masatoshi Suzuki), received the "Monozukuri Award" at the 58th "Top Ten New Products Award" hosted by the Nikkan Kogyo Shimbun in 2015. [About the portable grounding electrode "Kappa-kun"] This product can be used as a simple grounding electrode by permeating the moisture-retaining material filled in the main box into concrete. It can be used as a grounding electrode for preventing electric shock when operating aerial work platforms or heavy machinery, or as a supplementary electrode during grounding resistance measurements, easily achieving stable grounding resistance.

At Showden, we have opened a product page for "power-related products" that support stable power supply to information and communication equipment. We offer a lineup of products including DC power supplies, distribution boards, UPS, and backup power supplies, along with abundant product information such as features, main application areas, specifications, and dimensional drawings. Please take a look at the functional comparison chart and power system diagrams as well.

The Japan Patent Promotion Association, a public interest incorporated foundation, has awarded the Invention Promotion Contribution Award to Sho Ota, the chairman of Showden. [Reason for the Award] He has made significant contributions to the promotion of inventions and the development of the association. October 2005: Councilor of the Japan Patent Promotion Association October 2007: Director of the Japan Patent Promotion Association October 2009: Executive Director of the Japan Patent Promotion Association October 2013: Permanent Director of the Japan Patent Promotion Association To the present.

At the "41st Invention Awards" hosted by the Japan Invention Promotion Association and the Nikkan Kogyo Shimbun, Deputy Manager Kensuke Kaiuchi and two others received the Contribution Award for their invention, "Abnormal Detection Circuit for Communication Surge Protection Devices." **Award Points** The circuit for a communication surge protection device (SPD) that protects communication equipment from lightning allows for easy detection of abnormalities such as deterioration by sensing leakage current. It can detect issues without affecting the communication line by applying voltage to the SPD, and it can detect the deterioration of multiple SPDs using a single DC power supply. Since the deterioration and failure of the SPD can be monitored continuously, regular inspections are no longer necessary, leading to reduced inspection costs. Additionally, early detection and recovery of failure points become possible, which contributes to the reliability of the communication system.

Showden Co., Ltd. (4-3-8 Taihei, Sumida-ku, Tokyo, President and CEO Mitsuaki Ota) will launch the lightning protection product for photovoltaic (PV) systems, the PV SPD "ADN Series," starting in April 2013. The ADN Series is an SPD that protects the power conditioning system (PCS), solar panels, junction boxes, and collection boxes from induced lightning and direct strikes that enter the DC system of PV systems. The PV market has rapidly expanded since the introduction of the "Feed-in Tariff System for Solar Power Generation" in July 2012. Additionally, a survey by NEDO (New Energy and Industrial Technology Development Organization) indicates an increasing trend in the number of PV damage incidents caused by lightning. According to the latest data (2008), approximately 28% of all damages are attributed to lightning, which poses risks not only to expensive equipment like PCS but also to power generation interruptions. Showden has developed lightning protection products to safeguard PV systems from lightning damage and enable safer system operation. The PV SPD "ADN Series" features an internal separation mechanism that safely disconnects the SPD elements from the DC system in the event of degradation or failure due to lightning. It is a high-end model equipped with plug-in capability, SPD degradation indicators, and alarm outputs.

The December issue of Nikkei NETWORK features a special article titled "Tips for Reducing Network Equipment Failures (Lightning and Static Electricity)," which includes an interview with Aizawa from Showden's Lightning Protection System Department.
