In the state of Victoria at least, you can do a bit by visual <br>
inspection. With timber poles, the voltages typically are 415v 22kv <br>
and 66kv. If it feeds houses and shops its 415v. If it feeds into pole <br>
mounted transformers (with 415v out) its 22kv. If it feeds into small <br>
suburban sub stations (22kv output) its 66kv.</p>
<p dir="ltr">The 66kv comes from the really big sub stations which are fed from the <br>
steel towers. Steel tower voltages typically 220kv, 330kv and 500kv. <br>
The snowy mountains link is 330kv. 500kv are 3 conductors in a <br>
horizontal configuration, each conductot a bundle of 4 conductors.</p>
