I have been doing research about the name of these electric meters. I found a rough definition of it, but i have been told the name is not right.
the definition goes as follow:
"Macrometers are meters that perform a function similar to customer meters, but are attached to a public distribution transformer that feeds a secondary network.
These measurement equipment allow a comparison to be made between the total energy registered at the transformer terminals, with respect to the sum of the energy registered from the meters of the electrical services connected to that transformer, facilitating what is known as a Low voltage energy balance. The difference between the two values is known as energy loss."
I would like to know the specific name of the mentioned meter.
