[talk-au] Sources for power line details, NSW

Hi
In the state of Victoria at least, you can do a bit by visual  
inspection. With timber poles, the voltages typically are 415v 22kv  
and 66kv. If it feeds houses and shops its 415v. If it feeds into pole  
mounted transformers (with 415v out) its 22kv. If it feeds into small  
suburban sub stations (22kv output) its 66kv.

The 66kv comes from the really big sub stations which are fed from the  
steel towers. Steel tower voltages typically 220kv, 330kv and 500kv.  
The snowy mountains link is 330kv. 500kv are 3 conductors in a  
horizontal configuration, each conductot a bundle of 4 conductors.
