5.1. Current inputs
All current inputs are galvanically isolated (internal current trans-
formers). The meter is suited to operate together with external
measuring current transformers. Displayed values of currents as
well as their derivative values are automatically calculated using
set ratio value of the external transformer. Current inputs are
specified in the order as either 1 A or 5 A.
5.2 Voltage inputs
Displayed values of voltages as well as their derivative values
are automatically calculated using set ratio value of the external
transformer. Voltage inputs are specified in the order as either
3 x 57,7/100 V, 3 x 230/400 V or 3 x 290/500 V.
