Main functions of three phase split phase measuring multi-function electric energy
meter (DTSD581):
1) Measure energy: measures total, peak, shoulder and trough accumulative active
energy of three phase, measures total, peak, shoulder and trough active energy
of phase A, B and C respectively, and measure total reactive energy and reactive
energy of phase A, B and C respectively. The record content is current and previous
six months
2) Measure demand: measures total maximum demand and the occurred time of active
energy for current and previous 6 months
3) Tariff and time period: three tariffs for active energy (peak, shoulder and trough),
and can set at most 8 time periods per day
4) Real time data: voltage and current for phase A, B and C respectively, and active
power, reactive power and power factor for each phase and total
5) Records the latest ten times of starting and ending time of the power off for
the electric meter
6) Records each phase's phase loss accumulative time and times and its latest ten
times of starting and ending time
7) Records the accumulative time of the cover opening and the latest opening time
8) Has key-press display and automatic recycle display and the recycle display content
and time can be set
9) Records the load curve: selected from the total active energy and total reactive
energy, and the recording time interval can be set
10) Freezes billing readings on reading date at the end of a month, and also can
use broadcasting order to freeze the energy for current uniformly
11) Has controlling function: the output relay controlling interface is used to control
external device
Main functions of split phase measuring common meter (DTS581):
1) Records current three phase accumulative forward active total energy and reverse
active total energy, forward active energy of phase A, B and C respectively,
three phase accumulative forward inductive reactive energy (quadrant 1), and
forward reactive energy (quadrant 1+4)
2) Broadcasts the frozen energy
