Circuit overloads even when transformers limit its wattage

Think of a small transformer as a load of 1 kW in the circuit that it is receiving power from and a 1 kJ battery in the circuit that is sending the power to.  The input side of your transformer is in a circuit that uses conductive wire which has a maximum load before taking damage of 2 kW.  Considering that the transformer acts as up to a 1 kW load that leaves you 1 kW of power for whatever else you have in that circuit.  If you exceed 1 kW of power consumption of the other devices anywhere in the network that connects to the input side of the transformer and your transformer is not already full and it starts charging and drawing its 1 kW of power at the same time you will exceed 2 kW and melt your wire.

I have the same issue, seen here:

 

Transformer power rating should be 999w or something, or the actual overload situation should only happen at over 1010w / 2010w.

Thanks for the explanation. So the actual load of the conductive part is 2 kW for charging two PTs plus wattage flowing to the consumer heavy-watt part?

IMO this is a very strange behavior if transformers are meant to split circuits. The part between OUTs and INs should'nt know if there are any power consumers on the low side of INs.

This is still an issue. It's only the wire bridge that's having the problem. If you look on the right in the picture you see that it's a rounding issue. They are rounding up when adding the wattage. In actuality the power should be 666.66666666.... because they're rounding up at the second digit, any multiple of 3 such that Transformers Built = 3(3n-2) so {3,12,21,30,...} will break the wires. In my setup I had three, so 666.67 x 3 = 2000.01 which is above the strict 2000 limit. They should be rounding down in this situation, not up, or adding tolerance to avoid this. Increase the total to 2000.10 but don't add it to the tooltip... problem solved.

 

Don't have {3,12,21,30,...} transformers active at once on 1 wire until this is addressed.

Changed Status to Known Issue

Thanks for the report! We'll try figuring out what's happening here.

Changed Status to Fixed

Changed Note: to Found and fixed an issue causing Transformers to supply more power downstream than their advertised rating
