GPS Based Overhead Equipment (OHE) is to helps identifybad running locations to ensure the safety of trains, as well as the riding comfort of passengers. For smooth operation of locomotive, the movement of pantograph should be unobstructed on the contact wire.
The pantograph is the link between the overhead contact wire and the power circuit of the electric locomotive through which the required power is transmitted. It is essential to carry out proper maintenance of this equipment to improve the reliability of the pantograph, life of the OHE contact wire and to eliminate cases of panto entanglements.
Entanglement of pantograph with OHE normally takes place due to mechanical problems either in the OHE or with the pantograph. Entanglement can also take place during an accident or rough weather such as storm etc. Pantograph entanglement causes damages to the pantograph and overhead equipment results to stop the train
