Electric Grid

An overhaul of the electric network, engineer an Electric Grid.

See license.txt for credits to the developers and their work that came before.
A special thanks to Stringweasel for his work on Fluidic Power, the inspiration.

Important notes:
The electric network overhaul should only be added to a new or early game, it significantly modifies the electric poles.
If quick on/off via the circuit or logistic networks is not a priority, set "On tick interval" setting to 0 for near zero UPS impact.
Comments and suggestions are welcome.

May not be useful or functional on Fulgora (to be determined, possible future development).
The wiring rules should still be valid. However, the use of transformators, maybe not so much.

Adds:
Transformator
Huge electric pole
Underground substation
Circuit pole

Removes:
Power switch

Changes:
Small poles are the new medium poles
Medium, big, huge and circuit poles have no supply area and optional lights

Wiring rules:
Small poles can connect to small and medium poles
Medium poles can connect to small and medium poles
Big poles can connect to big poles, substations, underground substations, and circuit poles
Huge poles can only connect to huge poles
Substations and underground substations can only connect to big poles
Circuit poles can connect to circuit poles and big electric poles
Transformators can only connect to medium, big and huge poles

Small poles and substations are for power distribution and collection
Medium, big and huge poles are for power transmission only
Substations and underground substations are fast-replaceable
Circuit poles create copper wire connections for performance considerations, but are hidden

If Space Age is active, the electric network overhaul requires either the No More Quality or No Quality mods.
Startup setting to disable the electric network overhaul, effectively Transformator Only.

Transformators can be controlled via the circuit and/or logistic networks.

Set the Fluid filter to special fluids to manually enable and disable.
Selectable power rating (1MW to 10GW)

Transformators do function as expected if connected in parallel.
Very similar to Electric Transformators but a little different.
Do not place the transformator in the supply area of an electric pole.

Limitations:
Quality adds a supply area to poles intended to have zero supply area (medium, big and huge).
Hopefully future API development and/or my knowledge will allow for a better solution.

Recommended Mod:
No More Quality - Removes the Quality mechanic, resolves the issue with transmission only poles.

Supported Mods:
AAI Industry - Support for the small iron electric pole
Cargo Ships - Support for the floating electric pole
No Quality - Support for enabling the electric network overhaul
