FIELD: electric engineering, in particular, instruments which check characteristics of railway automation relays during their manufacturing and use. SUBSTANCE: relay winding is connected to direct current power supply and is supplied with direct current. Then after measuring its result is processed by computer. During measuring, function of current transient process when relay is fired is detected; moments of switches of relay contacts are recorded. EFFECT: increased functional capabilities. 3 dwg
