Efficiency of the transportation system is an indicator which shows the development of the
country. In Sri Lanka 20 percent of passengers use train transportation. Recently demand for
rail transportation systems has been increased with the increment of rail transportation
facilities. As more than 40 percent of employees use rail transportation passenger
transportation is the main target of Sri Lanka Railways than the good transportation.
Railway signaling system is to cater the traffic requirements by utilizing the limited resources
like trains and tracks. The loss due to failure of signal system is uncountable as human lives
and human hours loss except to the loss of damages to properties.
Train detection is a main input for reliable signaling system. DC track circuits are used in Sri
Lanka Railway signaling system to detect train on rails. In this scenario the current flow
through rails is in milliamphere range.
Induced voltages due to external forces could be affected to change the current value and
direction of power flow. This postgraduate research thesis describes the effect of
electromagnetic interference on track circuit due to transmission lines and further effect due
to electrification systems.
Electromagnetic interference level was measured under the different transmission lines and
suitable model was selected to further calculations. Safe margin levels was introduced to keep
with tracks for rated current flows. |
