PURPOSE: A system for measuring a physical quantity of a current collector for an electric railway is provided to accurately analyze collection performance of a pantograph apparatus according to a traveling state of a vehicle by sensing a train state signal in real time. CONSTITUTION: An accelerometer(12) measures an acceleration of a fan head of a current collector. A first signal converter(14) receives a physical quantity measurement signal and converts the received signal into a digital signal. A telemetry transmission unit(16) transmits the physical quantity measurement signal converted by the first signal converter to thee train through telemetry. A power supply unit(18) supplies power to various measurement sensors, the first signal converter, and the telemetry transmission unit. A telemetry receiving unit(20) receives the physical quantity measurement signal transmitted from the telemetry transmitting unit according to a plurality of channels.
