Doubt with medium voltage blades

Good afternoon. I wanted to know what happens if these medium voltage blades that go to the transformer are disconnected. Does it leave the three phases that leave the transformer without energy? Or does it also leave other transformers in the area without energy? I don't know if I explain myself well with the second question. I leave a photo to see the blades of which I speak: Thank you Regards!

Hello Facundo, these blades are disconnectors, so you can (or not) section one or more transformers or loads, this according to the design of the power line. In the case that you consult, you will most likely cut off the power supply to a particular transformer (this given the usual characteristics in urban distributions) but beyond that assumption, it is not possible to give an exact answer. regards

Perfect. Then it may be that they stop supplying power to several transformers from the substation? I say this because the other day there was a crew performing a maintenance on a medium voltage line and they cut the power in almost the whole neighborhood.

The energy of an entire neighborhood can be cut off leaving a transformer (zone transformer) out of service; or it may be that this line has fed a series of individual low power transformers. If it can be.

Of course, if a single transformer in the area is left out of service, it also affects other transformers by simply interrupting the current in the mt lines, isn't it? I read it several times, but I think I understood
