What are the purpose of ground wires in overhead transmission lines?

Ground wires are bare conductor supported at the top of transmission towers. They serve to shield the line and intercept lightning stroke before it hits the current-carrying conductors bellow. Ground wires normally do not carry current. Therefore they are often made of steel. The ground wires are solidly connected to ground at each tower. EEE Interview Tips  ...

Discuss Different types of Motors & their Uses.

Electric Motor An Electric motor is a machine, which converts electric energy into mechanical energy. The reverse of this is the conversion of mechanical energy into electrical energy and is done by an electric generator. Its action is based on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a mechanical force whose direction is given by Fleming’s Left-hand Rule and whose magnitude is given...
