Isolated from the original secondary current, voltage and power sensors

     High-speed trains, urban transport systems and freight trains and other public transport modes will provide the ideal solution to enhance the flexibility of transport, while reducing pollution and easing traffic congestion. Drive and control to solve the problems of these energy systems, power electronics is critical. The railway industry in the emerging technology have made new requirements, such as the demand for energy measurement, monitoring and motorcycles on the track continued to improve infrastructure maintenance problems.

      LEM products in the railway field Typical applications include:

 * the core of urban transport system converter (metro - tram - trolley bus)

 * monitoring of rail locomotives

 * Metro Station

 * inverters, converters, rectifiers

 • The auxiliary power supply

 * circuit breakers, transformers, DC path

 * control and safety systems

 Energy and Form

 * heavy locomotives, diesel generators

 * mine locomotive

     The use of precision electrical isolation design of the sensor range, and reliable. Current measuring range from 0.1A to the 20000A, the voltage measurement range from 10V to 6400V. It is able to protect the signals to the control signal and vehicle detection systems and turnout.

      LEM sensor electromagnetic compatibility certification by the CE, in line with EMC standards. The series of electrical parameters of the sensor and environmental constraints to standard EN50155, leakage and creepage distances to meet the standards EN50124-1 requirements under the insulation.
