Always specify the wiring mode and transformer ratings prior to setting up setpoints and analog outputs.
The maximum value for the product of the phase CT primary current and PT ratio is 57,500,000. If the product is
greater, power readings are zeroed.

Description
The wiring connection of the
device
The phase potential
transformer's primary to
secondary ratio
PT Ratio multiplication factor.
Used in extra high voltage
networks to accommodate the
PT ratio for 500 kV and higher
networks.
The nominal secondary line-to-
neutral (in configurations with
a neutral wire) or line-to-line
voltage (in 3OP2, 3OP3 and
3DIR modes) voltage. Used as
a reference voltage for the
EN50160 evaluation.
The primary rating of the
phase current transformer
The length of the demand
period for power demand
calculations. If the external
synchronization is selected, a
pulse front on the digital input
DI1 denotes the start of the
demand interval.
The number of blocks to be
averaged for sliding window
demands
The length of the demand
period for ampere, volt and
THD demand calculations
The nominal line frequency
The maximum demand load
current (0 = CT primary)
