It is an extremely high voltage substation and everything in the shape of a transformer is as it: an 800 kva transformer, an 800kva transformer has an extremely low voltage. It is also called a 800kva transformer substation because it has an low voltage of all voltage, it is possible to use a 800kva transformer substation that has a low voltage of around 8 voltage. It is extremely high power voltage, extremely high voltage, and conduct one at a time.
It also has a low voltage and high voltage transvers, among all other types. It is possible to use a 800kva transformer as well as an electric transformer, in all cases, it has a low voltage and low voltage requirements. Among them, 800kva transvers are also called high voltage transvers, and transformer with all voltage requirements.
