I might be wrong but it looks simple to me. Why not just put those rods deeper so it is below permafrost. I don`t know how deep this permafrost is, but if it is easy to get underneath it, you'll have as much efficiency as anywhere else(I am guessing the conductivity underneath is good) .
As a 3 phase system is designed, all currents of a resistive load cancel as the sum of all 3 voltages is 0. So for linear, 3 phase loads or a big amount of linear and consistent 12 phase loads, the total current on the neutral should be very low compare to phase currents.

Hi,
I've just learned how a SWER system works, but there's still a few things I don't understand. How can you get a decent efficiency with all your current going trough earth?
The ground must be a huge resistance for the current that has to go through many kilometers through ground to come...
Ok, I should have seen that the power supply supplies 24VDC to the PLC. Outside of that, it doesn't give me information. I forgot to mention that I have a display (PanelView 600)fed from that power supply with 24VDC and it works properly.
Hello Guys,
I am facing a very basic problem with the Micrologix 1500.
It is powered via a power supply connected to the PLC via a power cord. When I power it up, I get power to the power supply and its green light turns on. But there is no sign of power on the PLC side. All lights are turned...
As long as I know, you should choose the higher voltage available on site. This is simply a matter of decreasing the current in the motor, meaning smaller and cheaper wires.

As I am just out of school, I still don't understand a few things:
As I understand it, a slash breaker cannot be used for 3 wires equipment because it has to support line-to-line Voltage instead of just line-to-ground.
If I am right, then why do a 3W panel connected to a 4W solidly grounded...
