Large power transformer

The problem is that the output is actually not limited. It works as a simple battery with one-direction flow. The small transformer has the same problem. One of mine small transformer create an overload on a 2 kW cable quite often.

So, for example, if we have one small transformer connected to some load of 4 kW or more, when it is turned on, it tries to output as much energy as it has, in this case, it has 1 kJ, and it does so in one tick, creating a load of 4 kW on this first tick. After that it only has about 250 J left (the input is actually limited to 1 kW or 250 J per tick) so it cannot output more than 1 kW from that moment. But when you turn it off for 3 ticks or more and turn it on again, the overload occurs again. Again and again. The more often it is toggled, the more often an overload happens.

A simple way to create overloads from nothing:

Are you able to overload the small transformer with no batteries on the load side?  I put 28kW of load on a small transformer and it never turned on more than 1kW of those loads.
