Home / Can relay protection be handled by a microcomputer
A microcomputer protection and control device is an intelligent secondary power system that integrates relay protection, real-time monitoring, automatic control, and communication functions. What is a microcomputer relay protection tester? Simply put, a microcomputer relay protection tester is a professional instrument used to test the functionality, performance, and accuracy of relay protection devices. It can simulate various operating conditions of the power system, such as normal. It is like the "doctor" of the power grid, detecting and eliminating potential health hazards in a timely manner through precise "physical examinations" to.
