If the power lines were Direct Current, sometimes used for efficient long distance transmission, then your compass would definitely be affected, and may be quite useless. The high currents in such a long distance DC line will generate a magnetic field. With an Alternating Current power line, the alternating current itself should not cause any problem with the compass, but the steel of the towers themselves may certainly do so.
In a DC circuit yes. The compass detects the magnetic field around the wire. Reverse the DC current and the compass will swing 180 degrees from the position is was in.
