BGX501-742-R01, APEX100 User Manual
5.3.11 Daily Energy Snapshots
Apart from the above mentioned eight TOD MD registers, a separate register is available to record the
maximum demand during the entire day (i.e. 00-24 hours) known as universal demand register. This is not
configurable through tariff.
5.4 Load survey
Load profiling of energy and instantaneous parameters are fixed at factory end, and these can‟t be changed at
run time. Survey integration period is fixed in tariff as 15 minute and it will be same for all the selected survey
parameters.
The meter is BIS compliant and supports minimum 22 days load survey data.
The memory can store up to 150 days for 10 parameters @ 15 min SIP.
Energy parameters available for selection:
1. Active Energy - Import
2. Active Energy - Export
3. Reactive Import while Active Import – Q1
4. Reactive Import while Active Export – Q2
5. Reactive Export while Active Export – Q3
6. Reactive Export while Active Import – Q4
Instantaneous parameters available for selection:
1. Average Frequency (Average value of Instantaneous Frequency for SIP duration)
2. V1 – R Phase Voltage (Average value of Instantaneous R Phase Voltage for SIP duration)
3. V2 – Y Phase Voltage (Average value of Instantaneous Y Phase Voltage for SIP duration)
4. V3 – B Phase Voltage (Average value of Instantaneous B Phase Voltage for SIP duration)
Notes:
5. Time Set scenario
6. On forward time set within a day will not trigger new day opening in load survey.
7. On forward time set beyond the day will trigger new day opening in load survey.
8. On backward time set within a day or beyond the day will open new survey day. In this case more than one
entry will be available for same day.
9. In case of feeder fail load survey will be treated as power fail and all SIP data will be logged as zero.
