You can prepare the following table:
1.14 TEST OF ENERGY METERS
Energy meters can be single phase or three phase; in the
second case, with three or two equipments. As T1000 PLUS is
a single phase generator, it is possible to test single phase
meters, or three phase with three or two equipments,
provided that voltages are connected in parallel and currents
in series.
The following connection scheme shows the connection of
current, AC voltage, DC voltage to the energy meter under
test, and also to a sample meter. This scheme applies to all
classes of energy meters, the accuracy range being given by
the sample meter. For less accurate tests, class 2 or more, it
is possible to avoid the use of the sample meter.
