- FY2021AdvancedAnnual report
「We launched a main-circuit seismic circuit breaker suited to renovations of residential distribution boards, contributing to the prevention of electrical fires when earthquakes occur.」
The seismic circuit breaker initiative has progressed from proof-of-concept testing to product launch and wider adoption. - FY2020AdvancedAnnual report
「We are also conducting a proof-of-concept test aimed at commercializing “Galsearch,” a high-functionality seismic circuit breaker targeting small and medium-sized buildings. Data from earthquake sensors installed on multiple floors is aggregated and processed using power-line communication technology, and the circuit breaker is shut off to prevent electrical fires caused by power restoration.」
The high-functionality seismic circuit breaker initiative has expanded from residential-focused testing to testing aimed at commercializing a product for small and medium-sized buildings. - FY2019AdvancedAnnual report
「In June 2018, we began a proof-of-concept test with Kakegawa City, Shizuoka Prefecture, as a “Regional Disaster-Prevention System Proof-of-Concept Project.” Seismic circuit breakers and measuring instruments were installed at 23 cultural properties and public facilities in the city to prevent electrical fires caused by power restoration after an earthquake and to analyze waveform data on ground motion and its magnitude.」
The proof-of-concept test of high-functionality seismic circuit breakers has progressed to installation at 23 locations in Kakegawa City and data analysis as part of a regional disaster-prevention system with a local government. - FY2018AdvancedAnnual report
「In the proof-of-concept test of high-functionality seismic circuit breakers (earthquake and lightning IoT) that we began in 2016, we are providing the data obtained for use in a project to strengthen resilience against disasters. We have also begun a new proof-of-concept project with local governments for regional disaster-prevention systems using high-functionality seismic circuit breakers, and are working to support safe living in local communities.」
The initiative has expanded from residential installation and data collection to providing accumulated data to external projects and conducting a proof-of-concept test of a regional disaster-prevention system with local governments. - FY2017First statedAnnual report
「This project is demonstrating a system that attaches sensors to seismic circuit breakers and surge arresters installed in residential distribution boards, uses IoT technology to collect and analyze earthquake and lightning data in the cloud, notifies residents of damage by email, and uses big data collected from a large number of homes for disaster preparedness. Installation work is underway at approximately 100 homes in the Tokyo metropolitan area, and data collection has begun.」
A proof-of-concept test combining sensors on seismic circuit breakers and surge arresters, cloud-based data storage and analysis, damage notifications, and disaster-prevention applications has begun, with installation at approximately 100 homes in the Tokyo metropolitan area and data collection underway. The third-party committee consists of 9 experts.
