FIELD: measuring equipment.
SUBSTANCE: invention relates to devices for measuring electrical power. A device for measuring electrical power supplied to a railway vehicle along a high-voltage power supply line contains means for resistive voltage division, the first processing means for formation of signals indicating voltages of the power supply line, means for current measurement, and the second processing means for formation of signals indicating amperage. At the same time, the first processing means are made with the possibility of calculation of power. Means for resistive voltage division contain several voltage dividers functionally connected to the power supply line and forming separate corresponding paths of connection to the specified contact grounding terminal. The first processing means contain several separate processing modules, each of which is connected to the corresponding one of connection paths and is made with the possibility of formation of signals indicating voltage of the power supply line.
EFFECT: improvement of voltage measurement, as well as improvement of device resistance to malfunctions.
