Automatic testing of various types of residual current circuit breakers 'Automatic Testing System for Residual Current Circuit Breakers'
Control all devices with software and conduct tests automatically. Capable of handling not only standard tests but also manufacturer-specific tests!
■Sensitivity current test ■Operating time test ■Single-phase fault operation overvoltage test ■High-frequency superposition test ■Frequency sweep test, etc., are conducted automatically! Since manual machine operation is not required, the test results do not vary depending on the tester, which helps prevent the personalization of tests. ●Complies with JIS C 8201-2-2 (IEC 60947-2) standard tests ●Select the test items to be conducted via software and input the test conditions to automatically perform the tests ●Achieves a speed test from start to finish, including result display, in as fast as 5.5 seconds ●Test results are automatically converted to CSV format, allowing for time-saving in report management ●Real-time measurement of test current, voltage, and time using a power meter and waveform recorder. After completion, the values at the trip time and the waveforms before and after the trip are displayed on the software screen ●The test circuit and measurement values are displayed on the software screen, enabling smooth testing while understanding the circuit configuration.

Company information
Since the time of the Sunshine Project at the current Ministry of Economy, Trade and Industry, we have developed simulated power sources, measuring instruments, power conditioners, and more, in response to requests from organizations such as the National Institute of Advanced Industrial Science and Technology, the Central Research Institute of Electric Power Industry, and Tokyo University of Agriculture and Technology. Based on these achievements, we have commercialized our products and expanded sales to various research institutes and manufacturers, proudly positioning ourselves as a niche leader in this field. We specialize in the development of products and systems that combine hardware and software, including simulated power sources such as solar cells and storage batteries, load devices necessary for grid connection testing, and testing systems that operate these components collectively. We also have extensive experience in solar cell measurement, and our I-V curve tracer is widely used not only for the maintenance of solar power plants but also for research and development purposes at manufacturers, research institutions, and universities. We have numerous delivery records of automated measurement systems that incorporate measuring instruments and load devices. Development of power electronics equipment that combines analog and digital technologies, development of control software using DSP, and construction of PV measurement systems are among the services we offer, tailored to meet our customers' needs.
