Electric Transmission System basically takes the power from power plant and transfer it to a substation installed near a populated area. The electric power is transmitted over long cables called Transmission Lines. These transmission lines travel a distance of hundreds of kms to carry the power from generating station to load center. Over such a wide range of transmission network, faults are bound to occur. Fault is an abnormal condition in which the undesired value of current flow through an unintended path. These faults ...

Electric Transmission System basically takes the power from power plant and transfer it to a substation installed near a populated area. The electric power is transmitted over long cables called Transmission Lines. These transmission lines travel a distance of hundreds of kms to carry the power from generating station to load center. Over such a wide range of transmission network, faults are bound to occur. Fault is an abnormal condition in which the undesired value of current flow through an unintended path. These faults need to be sensed and faulty part should be disconnected from the system quickly so as to stop such high current to flow for considerable period of time and cause overheating and insulation failure in the equipments as well as to restore continuity of power quickly.
