<p>The device has a transformer whose core encloses a transmission line, where the core extracts electric energy from a current carrying conductor of the transmission line for supplying the energy to a control electronic and an electric motor. The control electronics and the motor are connected with the transmission line in a force-fitting manner, where the device is automatically activated and electro-magnetically driven in a cyclic movement along the transmission line, when a preset weather condition is reached.</p> |
