Abstract

The invention discloses an electric energy meter for an electric locomotive, which comprises a data recording and processing module, a power module, an electric energy metering module and an inductive measuring device, wherein the electric energy metering module is connected with an alternating-current electric wire. The power module is connected with the data recording and processing module, the electric energy metering module is connected with the data recording and processing module, and the inductive measuring device is connected between the alternating-current electric wire and the electric energy metering module. The electric energy meter avoids the impact of high voltage and high current coming down from a pantograph on the electric energy metering module, so that accuracy of electric energy metering data is ensured.
