Best-Selling Intelligent Protection Relay Tester - KF86 Intelligent Relay Test Set – Kingsine Detail:


With analog (6x310V voltage, 6x30A current) and IEC61850 SMV messages simultaneously output.
Built-in dual-core CPU industrial computer, built-in large-capacity SSD solid drive; operating system Embedded Windows 7; 9.7-inch true color LCD screen, 1024×768 resolution, touch screen operation. Can work offline or online;
Provide 8 pairs of LC optical ports, can transmission and receive 36 channels of IEC61850-9-1, IEC61850-9-2 frame format sample values; with optical power test function.
Provide 6 ST output optical ports and 2 ST receive optical ports, which can output 6 sets of sampled value messages conforming to IEC60044-7/8 (FT3) format; can receive 2 sets of FT3 format of IEC60044-7/8 specification Sampled value message;
Can subscribe/publish GOOSE information or output, receive switching, and realize closed-loop testing of protection;
Simulate 12-channel low level output to test the protection of low level input;
Start up to simulate the IED to actively release GOOSE, sampled value signals, to eliminate the reset process of the device under test caused by link interruption after the test is stopped;
The optical port output is sampled or GOOSE can be freely defined; multiple different GOOSE control block information can be subscribed/published;
Sample value channel function, the number of channels can be set freely, up to 36 channels can be configured;
Automatically import SCL (SCD, ICD, CID, NPI) files to realize automatic configuration of sampled values and GOOSE information, and save sample values and GOOSE configuration information as a configuration file for testing.
It can automatically detect optical digital signals from MU, protection device and intelligent operation box, and realize automatic configuration function of sampling value and GOOSE information;
Can simulate abnormal conditions(loss, misorder, quality abnormality, message re-transmission, data anomaly, out of step, etc.);
The channel quality of the output SV message can be set, and the simulation unit can be simulated and debug, set to invalid, set to run state, and can simulate double AD inconsistency and other tests.
Built-in GPS/Beidou timing module with GPS, IRIG-B code synchronization time function;
Full-featured software test module, AC, status sequence, recloser test, distance protection, overcurrent protection, inverse time overcurrent, zero sequence protection, ramping test, power direction, differential test, frequency test, synchronize test software modules
With the unit test function, you can test the unit’s precision, time accuracy, punctuality accuracy, and data transmission and testing functions.
Support the graphical display of SCD files, the instrument can graphically display the IED device interconnection relationship and virtual terminal connection.
With the IRIG-B code transmission function, when the external GPS is used, it can be used as a timing device.
