The key advantages of this bench-top tester include three-phase synchronous output, ensuring consistent test data for each phase, and a testing accuracy of ±0.2%, meeting the high-precision testing requirements of professional power teams. It comes with professional testing software that can automatically generate test reports compliant with power industry standards, reducing manual data processing work. The built-in Ethernet interface supports remote control via a computer, enabling batch testing of multiple devices. Compared to traditional three-phase testers, it solves the pain points of poor synchronization and low testing accuracy, greatly improving the efficiency of high-voltage substation maintenance.
This bench-top three-phase relay protection tester has dimensions of 500×450×250mm and a total weight of 28kg, with an ABS and metal composite body for enhanced durability. It supports AC 0-100A and DC 0-50A current output per phase, as well as AC 0-500V and DC 0-400V voltage output per phase, with 2-63 harmonic output functions to meet the testing needs of various high-voltage protection devices. It has a built-in thermal printer for on-site report printing, and can store up to 10,000 groups of test data. The working humidity range is 20%-80% non-condensing, and the body protection grade is IP20, suitable for standard laboratory and substation working environments.
This tester is mainly applicable to 10kV and above high-voltage substation operation and maintenance, large factory distribution system calibration, factory inspection of power equipment, and experimental testing of power research institutions. It is suitable for testing high-voltage circuit breakers, differential protection devices, distance protection devices, and other professional high-voltage protection equipment, and can meet the standardized testing needs of large power operation and maintenance companies, providing accurate data support for the safe operation of power systems.
