Showa Denko has developed a new service for lightning damage prevention in collaboration with Halex Corporation, called the Lightning Risk Monitoring System 'LiRiMoS'. The service has now been launched. It provides information on lightning occurrences and forecasts, automatically collecting, processing, and editing big data analyzed by the Japan Meteorological Agency, and offering it through a UI/UX that takes into account the characteristics of the information. By visualizing lightning risk, it can help customers reduce lightning damage and mitigate disaster in their businesses.

Showden Co., Ltd. has opened a "Solution Lab" within the SC Center (Koto Ward, Tokyo) as a demonstration environment to experience comprehensive solutions for enhancing the safety of important facilities, in conjunction with the relocation of the SC Center. In this facility, you can experience new network and security solutions, including a large display wall suitable for monitoring environments, a high-speed and high-precision contactless biometric authentication system, a high-definition surveillance camera system, and a wide-area wireless system capable of long-distance transmission, with the GENETEC Security Center as the core system. For more details, please visit our company website.

The "TMZ-1000" is a device that detects lightning strikes on wind power generation equipment, antenna towers, power supply lines, lightning rods, etc., and transmits contact signals while recording lightning current values, charge amounts, as well as the time and frequency of lightning strikes. It is capable of measuring lightning charge amounts and peak lightning current values, and recording the time and frequency of lightning strikes, as well as calculating the cumulative values of charge and current. It has a function to set a threshold for current or charge values in advance, and if lightning energy exceeds this threshold, it will trigger an alarm. 【Features】 ■ Detects lightning and transmits contact signals ■ Calculates cumulative values of charge and current ・ Measures lightning charge amounts (up to 1000 coulombs) and peak lightning current values (up to 200 kA) ・ Records lightning time and frequency (up to 999 times) ■ Triggers an alarm when thresholds are exceeded For more details, please refer to related products and catalogs.

Additionally, the "Materials & Downloads" section has also been renewed and is available for use without membership registration. Please feel free to utilize it as well.

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 linked, are a common challenge for all companies and organizations. In this seminar, we will mark the 10th anniversary of the Great East Japan Earthquake by clearly introducing the fundamental knowledge of earthquake measures, new countermeasure know-how, and case studies by facility type, in response to many requests from participants. By implementing the above, we will support the effective review of earthquake measures and disaster prevention plans.

At Showden, 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 easier to understand. We invite you to watch it.

At Showden, 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 allowing the moisture-retaining material filled inside the main box to permeate into the concrete. It can be used as a grounding electrode for preventing electric shock with 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 such as DC power supplies, distribution boards, UPS, and backup power supplies, along with abundant product information including features, main application areas, specifications, and dimensional drawings.

At the "41st Invention Awards" hosted by the Japan Invention Promotion Association and Nikkan Kogyo Shimbun, Deputy Manager Kensuke Kakiuchi and two others received the Merit Award for their invention, "Abnormal Detection Circuit for Communication Surge Protection Devices." 【Award Points】 This circuit for communication surge protection devices (SPD) allows for easy detection of abnormalities such as degradation by detecting leakage current, thereby protecting communication equipment from lightning. It can detect issues without affecting the communication line by applying voltage to the SPD, and it can detect the degradation of multiple SPDs using a single DC power supply. Since the degradation and failure of the SPD can be monitored continuously, regular inspections become unnecessary, reducing inspection costs. Additionally, early detection and recovery of failure points become possible, leading to improved reliability of communication systems.

Showden Co., Ltd. (4-3-8 Taihei, Sumida-ku, Tokyo, President 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 combiner 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 a rising trend in the number of PV damages caused by lightning. According to the latest data from 2008, approximately 28% of all damages are attributed to lightning, which poses risks not only for expensive equipment like PCS but also for 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 allows for the safe disconnection of the SPD element from the DC system in the event of degradation or failure due to lightning. It is a high-end model equipped with plug-in capabilities, 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.
