Pt
PT ratio
1.0∗ -
6,500.0
The potential transformer ratio
Ct
CT primary
current
1-50,000
(5*)
The primary rating of the current
transformer, in A
d.P
Power demand
period
(PM130E)
1, 2, 5,
10, 15*,
20, 30,
60, E
The length of the period for power
demand calculations, in minutes.
E = external synchronization
n.dp
Number of
power demand
periods
1-15
(1*)
The number of demand periods to
be averaged for sliding window
demands
(PM130E)
1 = block interval demand calculation
A.dP
Ampere/Volt
demand period
0-1800
(900*)
The length of the 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 sliding averaging
rSt
Reset
enable/disable
diS∗, En
Protects all reset functions, both via
the front panel or communications.
Freq
Nominal
frequency
50, 60 Hz
The nominal power utility frequency
Synchronization of the power demand interval can be made through
communications (see the PM130 Communications Reference Guides) or via
the front panel (see Section 4.9). If the power demand period is set to E, an
external synchronization pulse denoting the start of the next demand interval
can be simulated by using the synchronization command sent via
communications.
60 Hz default for North America; elsewhere, default is 50Hz.
NOTES
1) The maximum value for CT PRIMARY CURRENT × PT RATIO is
10,000,000. If this product is greater, power related values will be zeroed.
2) Always specify WIRING MODE, PT RATIO and CT PRIMARY
CURRENT prior to setting up alarm setpoints, otherwise the
alarm/event setpoints which use these parameters will automatically be
disabled.
