Quick question about Power Transformers

[marcjhune22]

What is the maximum power a transformer can take in its input?

[Fernir]

At least 20kW on input but will drain up to 1kW

[Kasuha]

On input, the transformer acts as a battery, except with a consumer priority (so it goes before actual batteries). There's no limit on power drawn and it doesn't count towards load on the wire. Which is something devs should look at but that's how it works at present.

attached 2 coal gens at the input of the transformer, no power wasted. but when i tried to connect 2 NGG to a transformer, there are no power loss but when I speed up the game, it reports too much power loss.

[Kasuha]

Power loss does not come from transformers. At least as far as I know. Wasted power is power generated by generators but not used by buildings that use power. E.g. if you attach a refrigerator (-120 W) to a coal generator (+800 W) you'll have 680 W wasted power.

It's also possible the game doesn't calculate it accurately, it's not something I paid too much attention to. Wasted power is usually inconsequential, while when you are low on power, that's where problems start.

from what I see there is somewhat a limit on how much power a transformer can accept via its input, when connected to a generator.

The transformer is limited by its battery - it cannot accept more than 1000 J per simulation tick. But that's a lot. Definitely more than the 1000 W you're supposed to be limited with on the transformer's output.
