Pt
PT ratio
1.0-6500.0
1.0
The phase potential
transformer’s primary to
secondary ratio
Pt.F
PT Ratio multiplier
Ч1, Ч10
Ч1
PT Ratio multiplication factor.
Used in extra high voltage
networks to accommodate the
PT ratio for 500 kV and higher
networks.
U.SEC Nominal
secondary
voltage
10-690 V
120 V
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.
Ct
CT primary current
1-20,000 A
5 A
The primary rating of the
phase current transformer
d.P
Power block demand
period
1, 2, 3, 5,
10, 15, 20,
30, 60 min,
E=external
sync
15 min
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.
nd.P
The number of
blocks in the sliding
window
1-15
1
The number of blocks to be
averaged for sliding window
demands
Ad.P
Ampere, volt and
THD demand period
0-1800 sec
900 sec The length of the demand
period for ampere, volt and
THD demand calculations
Freq
Nominal frequency
50,60 Hz
60 Hz
The nominal line frequency
LoAd Maximum
demand
load current
0-10000 A
0
The maximum demand load
current (0 = CT primary)
Ì
Always specify the wiring mode and transformer ratings prior to setting up setpoints and analog outputs.
Ì
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.
