功率计可以记录上面列出的增量能量数据。
记录的数据提供了分析所需的所有信息
能源和电力使用与当前或未来公用事业费率的对比。这个
这些信息对于比较不同的使用时间特别有用
速率结构。
使用增量能量功能时,请注意以下几点
记住:
•峰值需求有助于在以下情况下最小化数据日志的大小:
滑动或滚动需求。更短的增量能量周期
使重构负荷分布分析更容易。
•由于增量能量寄存器与
功率表时钟,可以从多个
电路并执行***的累加。
使用增量能源
增量能量累积在***的开始时间开始
并在***的结束时间结束。当开始时间到达时,a
新的增量能量周期开始。开始和结束时间为:
从午夜开始以分钟为单位***。例如:
间隔时间:420分钟(7小时)
开始时间:480分钟(上午8:00)
结束时间=1440分钟(下午12:00)
***次增量能量计算将从上午8:00至3:00进行

The following procedures tell how to set up conditional energy for
command interface control, and for digital input control. The
procedures refer to register numbers and command codes. For a
listing of power meter registers, see Appendix A—Register List on
page 124. For a listing of command codes, see Table B–2
on page 207 in this chapter.
Command Interface Control
• Set Control—To set control of conditional energy to the
command interface:
1. Write command code 9020 to register 8000.
2. In register 3227, set bit 6 to 1 (preserve other bits that are
ON).
3. Write 1 to register 8001.
4. Write command code 9021 to register 8000.
• Start— To start conditional energy accumulation, write command
code 6321 to register 8000.
• Verify Setup—To verify proper setup, read register 1794. The
register should read 1, indicating conditional energy accumulation
is ON.
• Stop—To stop conditional energy accumulation, write command
code 6320 to register 8000.
• Clear—To clear all conditional energy registers (1728-1747),
write command code 6212 to register 8000.

Digital Input Control
• Set Control—To configure conditional energy for digital input
control:
1. Write command code 9020 to register 8000.
2. In register 3227, set bit 6 to 0 (preserve other bits that are
ON).
3. Configure the digital input that will drive conditional energy
accumulation. For the appropriate digital input, write 3 to the
Base +9 register. See the digital input templates in Table A–3
on page 124 in Appendix A—Power Meter Register List
on page 121.
4. Write 1 to register 8001.
5. Write command code 9021 to register 8000.
• Clear—To clear all conditional energy registers (1728–1747),
write command code 6212 to register 8000.
• Verify Setup—To verify proper setup, read register 1794. The
register should read 0 when the digital input is off, indicating that
conditional energy accumulation is off. The register should read 1
when conditional energy accumulation is on.
Incremental Energy
The power meter’s incremental energy feature allows you to define a
start time, end time, and time interval for incremental energy
accumulation. At the end of each incremental energy period, the
following information is available:
• Wh IN during the last completed interval (reg. 1748–1750)
• VARh IN during the last completed interval (reg. 1751–1753)
• Wh OUT during the last completed interval (reg. 1754–1756)
• VARh OUT during the last completed interval (reg. 1757–1759)
• VAh during the last completed interval (reg. 1760–1762)
• Date/time of the last completed interval (reg. 1763–1765)
• Peak kW demand during the last completed interval (reg. 1940)
• Date/Time of Peak kW during the last interval (reg. 1941–1943)
• Peak kVAR demand during the last completed interval (reg. 1945)
• Date/Time of Peak kVAR during the last interval (reg. 1946–1948)
• Peak kVA demand during the last completed interval (reg. 1950)
• Date/Time of Peak kVA during the last interval (reg. 1951–1953)

The power meter can log the incremental energy data listed above.
This logged data provides all the information needed to analyze
energy and power usage against present or future utility rates. The
information is especially useful for comparing different time-of-use
rate structures.
When using the incremental energy feature, keep the following points
in mind:
• Peak demands help minimize the size of the data log in cases of
sliding or rolling demand. Shorter incremental energy periods
make it easier to reconstruct a load profile analysis.
• Since the incremental energy registers are synchronized to the
power meter clock, it is possible to log this data from multiple
circuits and perform accurate totalizing.
Using Incremental Energy
Incremental energy accumulation begins at the specified start time
and ends at the specified end time. When the start time arrives, a
new incremental energy period begins. The start and end time are
specified in minutes from midnight. For example:
Interval: 420 minutes (7 hours)
Start time: 480 minutes (8:00 a.m.)
End time = 1440 minutes (12:00 p.m.)
The first incremental energy calculation will be from 8:00 a.m. to 3:00
p.m. (7 hours) as illustrated in Figure B–2 on page 217. The next
interval will be from 3:00 p.m. to 10:00 p.m., and the third interval will
be from 10 p.m. to 12:00 p.m. because 12:00 p.m. is the specified
end time. A new interval will begin on the next day at 8:00 a.m.
Incremental energy accumulation will continue in this manner until the
configuration is changed or a new interval is started by a remote
master.

• Set up—To set up incremental energy:
1. Write command code 9020 to register 8000.
2. In register 3230, write a start time (in minutes-from-midnight).
3. For example, 8:00 am is 480 minutes.
4. In register 3231, write an end time (in minutes-from-midnight).
5. Write the desired interval length, from 0–1440 minutes, to
register 3229.
6. If incremental energy will be controlled from a remote master,
such as a programmable controller, write 0 to the register.
7. Write 1 to register 8001.
8. Write command code 9021 to register 8000.
