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.
Nominal secondary
voltage
The nominal secondary line-to-
neutral (in 4LN3, 3LN3 and
3BLN3 wiring modes) or line-to-
line (in 4LL3, 3LL3, 3BLL3,
3OP2, 3OP3 and 3DIR modes)
voltage. Used as a reference
voltage for the EN50160
evaluation.
The primary rating of the phase
current transformer
Power block demand
period
1, 2, 3, 5,
10, 15, 20,
30, 60 min,
E=external
sync
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 in
the sliding window
The number of blocks to be
averaged for sliding window
demands
Ampere, volt and THD
demand period
The length of the demand
period for ampere, volt and
THD demand calculations
The nominal line frequency
Maximum demand load
current
The maximum demand load
current (0 = CT primary)
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.
