POM2-3333 could be used for testing various kinds of digital protection relays and different types of MU with electronic transformer input, magnetic transformer input and electromagnetic transformer input, integrate with reliable analog output and high-speed digital signal process. It is with 0.05% high accuracy of analog outputs and strong abnormal SMV function.
For testing MU, it could do the following testings.
SMV accuracy test
Check MU amplitude,frequency,phase error between the current and volrage input and SMV output.
SMV channel delay
Check MU time delay between the current and voltage input and SMV output.
SMV Abnormal
Real-time analyze and statistics for the exceptions that will influence MU’s normal work, such as frame drop, disordering, repeat, out-of-step, SN deviation, and abnormal quality etc.
SMV dispersion
Real-time statistic on SMV interval.
GOOSE abnormal
Real-time analysis and statistics for the exceptions that will influence MU’s proper work, such as time of GOOSE deflection, time of TEST deflection, Sq loss, Sq repeating, St loss, St repeating, code error, invalid survival time, communication-timeout recovering time, and communication-outage recovering time, etc.
Synchronization accuracy
Test MU's the time synchronization accuracy between MU and POM2-3333.
Timekeeping accuracy
Test MU's time keeping accuracy after it is cut off the synchronization signal from test set and clock source.
Power Error
Test MU error range btween input power and output power.
Voltage Switch and parallel logic
Send disconnector place according GOOSE message or binary contact, and finish the test of PT voltage concatenation of MU and transferring of voltage.
SMV and GOOSE analysis
Analyze the SMV and GOOSE.
And besides MU testings, POM2-3333 also support all kinds of digital relay testings, such as Distance;Differential, Line differential,Auto-reclosing;Directional;Synchronization;Time inversed current/voltage;Frequency relay;Overcurrent/voltage, under voltage;Harmonics;CB Operate;Transplay for comtrade files,etc.
