The potential transformer ratio
U.SEC PT secondary
voltage
10 - 690
(120∗/400∗)
Nominal secondary voltage of the phase
potential transformer
Ct CT primary current 1-10,000A

The primary rating of the phase current
transformer
d.P Demand period 1, 2, 5, 10,
15∗, 20, 30,
60, E
min
The length of the demand interval (sub-
interval for sliding window demand) for
power demand calculations, in minutes.
E = external synchronization
n.dP Number of demand
periods
1-15
(1∗)
The number of demand sub-intervals to be
averaged for sliding window demands. A
product of the demand period and the
number of demand periods should not
exceed 60 min.
For block demand, set this value to one.
A.dP Ampere/Volt demand
period
0-1800 s
(900∗)
The length of the demand period for
volt/ampere demand calculations, in seconds
(0 = measuring peak current)
buF Averaging buffer size
8∗, 16, 32
The number of measurements for RMS
averaging
rSt Reset enable/disable
diS, En∗
Protects all reset functions, both via the front
panel or communications.
PrE.C
2
The number of pre-
event cycles for
waveform log #1
1-8 (1*) The number of waveform cycles to be
recorded before the event that triggered
waveform capture
rEc.C
2
The number of
cycles in a waveform
series for waveform
log #1
0 to 1280
(0*)
The total number of waveform cycles to be
recorded on any event occurrence. Will be
rounded to a nearest bigger number multiple
of 16.
Freq Nominal frequency 50, 60 Hz
1
The nominal power utility frequency
LoAd Maximum demand
load current
0-10,000 A
