A series-capacitance compensated shielding circuit is located physically adjacent and parallel to a polyphase power transmission line for the purpose of partially cancelling the electromagnetic fields created by current flow through the transmission line. The shielding circuit forms a loop circuit around substantially the entire transmission line or a portion thereof, and is positioned such that a current is induced therein by the magnetic field produced by the alternating currents in the transmission line. Such induced current is tuned by the series capacitance to produce an optimized cancelling magnetic field, thus reducing the net electromagnetic fields created by the power lines along a right-of-way.
