Hi there,

A friend of mine asks what happens on high voltage distribution lines
about
SWR at the distribution frequency (50/60 Hz). I'm stuck.

I understand that HV generators/transformers behave like voltage
sources and
not power sources. This means that conjugate impedances don't apply
here but
what about the existence of SWR on those kind of lines and the
possible
consequences on very long lines.

Anyone has an idea ?

I understand that excessive SWRs on the long-haul transmission lines
have brought entire grids down.
