Disclosed is a sensor tester for a railway vehicle. According to the present invention, the sensor tester for a railway vehicle comprises: a control unit for performing a performance test for an input current sensor (DCCT), an input voltage sensor (DCPT), a charger voltage sensor (BCPT), a charger current sensor (BCCT), an AC three-phase voltage sensor (ACPT), an AC three-phase current sensor (ACCT), and a current monitoring device (CMD) for a railway vehicle; and a display unit for displaying a result of the performance test performed by the control unit. According to the present invention, a structure and appearance test of variable voltage variable frequency (VVVF) and GEC vehicle voltage and current sensor types (six types other than DCCT), an input voltage variation test, an output current stability test, an output frequency stability test, a transient voltage characteristic test, an insulation test, and other performance tests can be performed.
