As air pollution becomes more and more severe, governments in many countries have set goals to implement or
convert transportation from fossil fuels to electricity.The railway industry is also evolving into new technologies using electricity and
complex & fast machines to ensure a sustainable environment for the present and the future.
OBTAINED EFFICIENCY AND RELIABILITY BY MONITORING THE CURRENT STATUS
Traction is driven by inverters and electric motors. It provides control and protection signals to power converters
and inverters that regulate energy to all electric motors and auxiliary equipment.
In this case, the current transformer is considered an important role in ensuring that the inverter and electric motor operate continuously and reliably.
This is because current pass through both transformers, circuit breakers, and train lines used for traction.
Therefore, how you control the input current affects the reliability of the equipment.
J&D Current Transducers provides various range of inner diameter and high-insulated voltage sensor for maximize the efficiency of
equipment by controlling the current passing through and delivering high-accuracy signals.
THE NEED OF VOLTAGE TRANSDUCERS
In the railway industry, voltage is related to cost and efficiency.
Accurate and reliable measurements are required to maximize the energy efficiency provided by the voltage network.
Therefore, J&D proposes Voltage transducers that measure a wide range of voltages.
