Device for determining electric energy provided to/restored by train via catenary system, has management and operating function calculating energy and energy consumption, and high and low voltage compartments connected by communication link

摘要

The device (100) has a data management and operating function (6) calculating supplied/restored electric energy and energy consumption based on data from measurement units formed of direct current voltage and current sensors (1, 2), voltage and current shaping devices (3, 5) and current sensor managing electronics (4). High and low voltage supplies (9, 10) of the measurements units and a man machine interface (11) are housed in a low voltage compartment (110) of insulator. The function is housed in a high voltage compartment (109). The compartments are connected by a communication link (7).
