- Power line frequency conversion stations are rare. There's a big one
- at Broken Hill, Australia, because the mines run on 40Hz (!). For most of
- a century, Broken Hill was electrically isolated, but a few years back,
- the power grid finally reached there, requiring a frequency conversion.
- Very messy. Big resonance problems. The mine has huge, intermittent loads
- with bad power factors. All solid-state, though; it's not done with
- rotating machinery.
