Hello I'm electrician from Poland. I'a looking for some photos about tower in power lines, distribution stations.I also want to know something about system in US (voltage levels) I've visited some cool site about your system but I have forgoten addres I would be gratefull if you help me.
No problem, You can use those photo's on your site.
I will make some more while on the road.
Also i will take some photo's from within the substations when i'm working there.
Standard voltages in New Zealand are: All at 50 Hz 220 kV, 110 kV, 66 kV, 50 kV, 33 kV, 25 kV, (Railways) 22 kV, 11 kV, 6.6 kV 3.3 kV 400 / 230 Volts supply 110 / 63½ Volts AC and DC in substations for metering and protection.
Then a 600 kV DC link is between the North and the South Island.
A 400 kV line is in the process of being built to supply Auckland
The product of rotation, excitation and flux produces electricty.
