BIden-Harris Regime Gave Ukraine Emergency Stockpile of Electrical Transformers
It sounds even more idiotic if you take in account that post-USSR grids are incompatible with US and even EU ones. You just can't take 60Hz US voltages transformers and put it in 50Hz post-USSR grid. It will not fit physically (which could be workarounded with a lot of effort), it will overheat due to lower frequency in post-USSR grid, and it will skew the grid because of inapropriate impedances. Also there will be other, less significant, but annoying problems too.
Grid transformers are not like universal USB chargers that will work with US 110V@60Hz, EU 240V/@50Hz and post-USSR 220V/@50Hz. They are heavily tuned at the design stage to specific parameters to be as safe as possible at specific high voltages and to minimize losses that cost a lot when you transfer megawatts.
Random regular 60Hz transformer you could find in home appliances could easily work at 50Hz and vice versa. But grid transformers are beasts where everything squeezed down for maximum efficiency.
Lower frequency need larger core and more turns in windings to have same efficiency and work without saturation. Grid transformer designed for 60Hz could easily saturate its core at 50Hz running on specified maximum power with unpleasant consequences. Less turns than needed (basically lower inductance) add more heat too.
If the US is installing smaller Gas Powered Generators in Ukraine to overcome blackouts would this newer system be 50hz or 60hz?
For local autonomous use it does not matter at all. Rare modern tech depends on grid frequency. As long as you provide voltage in range 200-240V, everything will be OK, even @100Hz.
Problems (and huge ones) will appear when you will end up with inevitable idea to connect this generators to the common country-wide grid.
Theoretically, you could use AC-DC-AC grid-connected converter to match grid and be able to properly send excess power to the grid, but this things are expensive, full of electronics and cant scale to the kilovolts and megawatts.
