My line voltage has been as high as 265 and 144 on a single.
Which is another nreason a lot of the big appliances now are marked 240\208.
Sorry for the hijack.
Kerry- the fuses between the upper lines and the transformer are for the 7200V distribution lines. Between the transformer and the houe are to protect the transformer from damage.(240V)

Of course. And the transformer for a residence is going to provide 120V on two legs that are 180 degree out of phase. That's the only possibility of getting 240V and 120V at the residence via three wires.
The reason an appliance is marked 240/208 is that the manufacturer is OK with it running on 120V split single phase or running it on 120V three phase. It has nothing to do with "voltage fluctuations".
