The present invention relates to a relay performance test system. A relay performance test system according to an embodiment of the present invention includes one or more connection parts to perform a performance test of a relay, and a relay part having a structure in which the relays connected to the connection parts sequentially or simultaneously perform a performance test; A measurement signal generator that generates current, voltage, and resistance signals to conduct a performance test of a relay connected to the relay, a voltage measurement unit that measures the minimum operating voltage and maximum recovery voltage of the relay, and the relay operation time and It includes a time measuring unit that measures the return time, and receives the test signal generated from the measurement signal generator and applies the test signal to the relay to test the relay’s performance, and controls the measurement signal generator and the process unit to control the relay’s performance. It includes an operation unit that manages the performance test and stores or outputs the data for which the performance measurement has been completed in the process unit, and the time measurement unit is a chattering measurement unit that can measure the chattering time at the contact point when measuring the operation time or return time. The chattering measurement unit measures the unstable time and fluctuating current until the current applied to operate the relay reaches the maximum value, and the operation unit measures the unstable time and fluctuating current measured by the time measuring unit. can predict the spring tension and lifespan of
