Study on Induction Electric Power Supply from the High Voltage Transmission Lines for the Wireless Intelligent Monitoring Equipment

It is expensive and difficult for the wireless intelligent monitoring equipment of high-voltage transmission lines to get and use electricity. There is a strong and changing magnetic field near the high-voltage transmission lines, which can he transformed into electric energy by induction coil. Firstly, it is necessary to verify whether the magnetic induction intensity is strong enough. Then the electromotive force, which is generated by the magnetic induction coil in such a magnetic field, is calculated and emulated in MATLAB. Lastly, the coil magnetic flux increases with the addition of the magnetic core and the electromotive force raises accordingly. The results show that the coil can he used in the vicinity of the high voltage line to solve the problem of high voltage line monitoring equipment's power supply.
