I am having trouble getting power out of my power-generating modules and to where it is needed. The power network topology looks like this currently:

boilers -> medium poll -> medium fuse -> [in : transformer : out] -> large poll -> [in : transformer : out] -> medium fuse -> medium poll -> mining drill

However, the boilers are running at a fraction of their capacity, the mining drills are drastically browning out and the large poll network is dipping in and out of yellow/green. One of my boiler cells is drawing a total of 3kw out through its transformer. It is a full 20:40 steam build, and has the capacity to generate enough power to keep the mining going. It just isn't making it out through the transformers.

Any ideas? Have I set things up wrongly? I have several of the boiler cells, so isolated them like this for when the power in the backbone is enough to burn out the medium polls.

I think I fixed it by manually pulling up the transformer by the power cell, putting it down again and re-wiring it

If you’ve got a save file demonstrating the problem, feel free to send it. Otherwise there’s probably not much I can do…

What you've done sounds correct though so it probably is a bug in the transformers.
