KF900A IEC61850 Relay Tester

● The smallest digital relay tester, 10.4 inch high-definition capacitive LCD screen, the whole machine full touch screen operation;
● Universal protection relay test function, With fully function of Manual test, state sequencer, Harmonic, recloser test , Line differential, Distance, Mutation distance, Overcurrent, Zero sequencer, Ramping, Power direction, Differential rate, Differential Harmonic, Overexcitation protection, Synchronize, Reserve power supply test, Busbar differential, Frequency test, Dv/Df test, etc.
● With MMS communication service function, Real-time monitoring sampling value,binary input/output, warning event of protection relay and measurement&control device. Support protection relay setting online reading,modify and setting area switch. Support relaying plate enable/disable,switch on/off.
● With secondary virtual terminal circuit auto test function, By sending SV and GOOSE message, and receiving MMS feedback which formed closed loop, realize automatic test of virtual terminals;
● Supports consistency check of IED device model files. Obtain the IED device model online through MMS, compare it with the local SCD model file, and get the consistency result of model;
● With background and substation control layer test function, by importing SCD file, it can simulate the protection, measurement & control device to send remote measure signal, remote control signal and other signals, access the station control layer network through MMS protocol, communicate with background and remote device, convenient and fast triggers all alarm events, changes the switch state ON or OFF, and current, voltage, and power values to achieve a point-to-point test with the monitoring background or the master station;
● Support importing substation Excel point table, obtain channel mapping configuration of remote measure signal and remote control signal through SCD file, automatically generate station signal point table, and directly transmit remote measure signal and remote control signal according to point number order;
● With SV, GOOSE message monitoring function. Real-time display of SV sample value amplitude, phase, frequency, waveform, vector and message source code, real-time display GOOSE virtual terminal status and message source code, record each virtual terminal turn over time and test GOOSE message transmission mechanism;
● Supports transmission delay, SV message integrity, SV output accuracy, merge unit dispersion of timing and punctuality accuracy measurement;
● Supports graphical display of SCD files, graphically displays IED device interconnections and connections of virtual terminal loops; with SCD file comparison function, and generates comparison reports;
● Real-time message receiver compared with the SCD file to achieve consistency check of the SCD file;
● Support recorder and PCAP file off-line analyze function, with PCAP message playback function.
● Support IRIG-B sending function, can be used as time source, with 6 channels separate fiber IRIG-B signal.
● Support Polarity checking function, support use DC method to checking polarity of protection/metering core of electromagnetic current transformer and electronic current transformer;
● With optical power measurement function, off-site phase detection function, built-in lithium battery power supply, working time is more than 8 hours continuously.
