This does not make any sense at all. Everyone here
says that the the requency is 50 Hz. I know the
electricity works at 50 Hz, this does not mean that
the electromagnetic waves of high power cable lines
are 50 Hz. For example, whenever I drive near high
voltage lines my am radio goes all haywire.

As others have made clear, this will be due to a problem with the power
lines.
One thing to remember is how easily AM (MW and LW) radio is interfered with.
So damn easy, in fact, that the RIS (Radio Investigation Service) have
outright refused to deal with any such interference complaints for several
years now.

This means that at least some of
the radiation is at 100 - 1600 KILO Hertz.

Once you get arcing, you get broadband noise which can interfere with any
receivers, radio or TV. AM receivers are more prone to such problems than FM
ones.
Such emissions are not to be relied upon for a reliable detection of power
lines. The nonexistence of such emissions does not mean that power lines are
not there.

I can't believe someone suggested to build
a 5000 km antenna to test these waves, I assume he was
making some sort of joke of my question. Obviously, any
detector should be smart enough to use a detection
method which doesn't involve builing a 5000 km antenna.

Have you thought about using a loading coil to shorten it
If you are referring to "Rick" <rick@skyko.com>, then he did not suggest you
actually do that, just that the wavelength was that size.

Not at all - all that means is that sufficiently strong 50 Hz
fields are capable of inducing noise in your radio. Surely
you don't believe that ONLY "100-1600 kHz" fields are
capable of affecting your radio, do you?

If the radio's any good, they are.

If you want to find overhead powerlines use a kite.

Those aluminaized mylar birthday balloons work much better. One landed
across the 12KV line where I live, took out the whole neighborhood for
over 8 hours. Just that silly little balloon burned out the transformer
and melted the 10 gage aluminum wire.

Soon, terrorists will be flying those little Mylar balloons with strips
of the silvery stuff hanging beneath in droves just to blow out power lines
everywhere. Imagine dozens of turban-wearing, box cutter carrying fellows
buying up loads of party balloons and dispersing all over in little VW
microvans to carry out their sinister plot!

Such radio equipment can easily be affected by electromagnetic waves outside
of the band they are intended to pick up. Because of this, the RIS have
refused to deal with complaints of interference to MW (AM) radio receivers.
Even with TV equipment, they assume the problem to be that the TV is being
affected by signals outside of the TV band, so they promote the use of a
braid breaker and HPF on the TV... which works in most cases.

Just because some equipment interferes with a receiver, it does not mean
that it is emitting waves within the band that the receiver is designed to
receive.
