The host uses a real-time operating system, which is fast, safe, and reliable, and is not easily attacked by computer viruses.
The newly designed software interface style can be operated offline or connected to an external computer. The operation of the host and the background machine is completely consistent and simple.
Rich test functions: state sequence, fixed value test, IT characteristics, simulated oscillation, whole group test, differential protection, harmonic superposition, low-frequency load shedding, synchronization device, metering instrument, GPS alignment, relay protection test system fault replay, and custom tests (special tests, 6~35kV comprehensive tests), etc. The relay protection test system fully meets the needs of users to test microcomputer protection and various types of relays. It can also conveniently complete tests on protection devices from foreign manufacturers such as ABB, Siemens, AREVA, and GE.
After the test, the test report of the relay protection test system can be easily exported from the USB port for printing.
