Metering
Load Profile Report
The load profile output has the following format:
=>>LDP <Enter>
FEEDER 1 Date: 03/03/99 Time: 21:58:06.875
STATION A Time Source: int
FID=SEL-734-X109-V0-Z001001-D20030227 CID=760E
# DATE TIME IA IB IC VA VB VC
1 *03/03/99 21:55:00 9.99 9.94 9.94 0.10 0.10 0.10
=>>
The SEL-734 places a “*” in the load profile report for any changes in date or
time (including Daylight Saving Time changes), if the meter cycles power, or
if TEST mode is entered during the recording interval for easy identification
in the report.
If the requested load profile report rows do not exist, the meter responds:
No Load Profile Data
Determining the
Size of the Load
Profile Buffer
The LDP D and LDP2 D–LDP12 D commands display the maximum number
of days of data the meter may acquire with the present settings, before data
overwrite will occur for the specified recorder.
=>>LDP D <Enter>
There is room for a total of 37 days of data in the load profile buffer, with room for
37 days of data remaining.
=>>
Clearing the Load
Profile Buffer
Clear the specified load profile report from nonvolatile memory with the LDP
C or LDP2 C–LDP12 C command. Changing the LDLIST setting will also
result in the buffer being cleared.
=>LDP C <Enter>
Clear the load profile buffer
Are you sure (Y/N)? Y <Enter>
Clearing Complete
Load Profile Retrieval
Using File Transfer
The SEL-734 supports Load Profile data retrieval using the YMODEM file
transfer protocol. The
ACSELERATOR QuickSet software uses this protocol to
rapidly and securely retrieve the SEL-734 LDP data. The YMODEM file
transfer LDP data is in secondary units scaled by 100 and rolls over at
999,999,999. The LDP report includes the CTR and CTR values which allow
post-read calculation of primary units.
The commands in Tabl e 4 . 16 describe how to retrieve LDP data over the
YMODEM protocol outside of
ACSELERATOR Quickset.
