1 MRI,BCS and Meter Information Integration by Vivek Pathak A specifically designed programme for Da Afghanistan Breshna Sherkat (DABS) Afghanistan 1

2 Technologies have evolved over a period of time and so have the meters 2

3 Conventional meters Meters conventionally measured a single quantity kwh kvarh kvah Meters were used for commercial purpose, (record consumption and bill to consumer) 3

4 This was the meter in good old days 4

5 The modern meter has evolved over time Today s meter is different from yesterday s meter What is the difference? 5

6 Today s meters are data loggers they churn out a lot of data They give much more than energy readings 6

7 Each meter can log a lot of data Data is useful, only if it is purpose oriented 7

8 Yesterday Single parameter (kwh) Single reading Manual reading Error prone Error prone again! Manual computation Today Multiple parameters Multiple readings (load survey) Electronic reading Less error prone Computers aid computations Less errors 8

9 Advantages of electronic meters More accurate than electromechanical meters They are data loggers & log time stamped data They are read electronically & human errors eliminated Remote reading is possible (LPR, PSTN, GSM, GPRS) They can detect & log illogical events (tampers) Appropriate for consumer end meters only 9

10 Yesterday, with electro mechanical meters Manual reading Consumption determined locally Today, with modern electronic meters Read electronically, not from display Complicated tariffs Consumption determined from computer, far away from meter Software (BCS) needed for data extraction This only extracts data from the meter 10

11 Metering system software meter has a large amount of data, not practical to read using display, better to read Electronically Third party application software or services are now needed Software supplied by meter manufacturers is not sufficient for deriving information from the data We will deal with Meter Reading and system software for meter reading/ data extraction. 11

12 Over view of Electronic meter Engineering plastic enclosure, better aesthetics LCD display with Backlight Rating plate Button for MD reset / reverse scrolling Calibration LED Inductively coupled RPU Optical Port for electronic reading Front side sealing arrangement Button for display scrolling / scroll lock Extended terminal Block (Transparent) Terminal Block 12

13 Information contained in modern electronic meters 13

14 Display & logged parameters Information in electronic meters can be classified as Display mode Auto display (for quick reference) Push button display (for detailed information) Logged parameters Instantaneous parameters Billing information Load survey Events or tampers Transactions 14

15 Display & logged parameters Information in electronic meters can be classified as Display mode Auto display (for quick reference) Push button display (for detailed information) Logged parameters Instantaneous parameters Billing information Load survey Events or tampers Transactions Scrolls automatically Displays Can be parameters accessed by for meter reader consumer viewing To see Can history be viewed data & tamper from information window when meter is Useful sealed to identify meters that need closer investigation Information is of consumer interest 15

16 Information in electronic meters can be classified as Display mode Auto display (for quick reference) Push button display (for detailed information) Self diagnostics LED Segment check Battery & NVM health RTC date & time Basic information Display & logged parameters Instantaneous parameters V, I, PF, kw, kvar etc. Power On/Off hours Rising demand with elapsed time TOU definition TOU wise MDs 6 or 12 history data Tamper information Missing potential Current reverse Short/Open circuit Meter serial no. Billing information Load imbalance Date/time in RTC Cumulative Registers Cum count of events 16

17 Logged Parameters 17

18 Logged Parameters Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions These are electrical parameters as seen by meter at the time of reading or can be read locally using MRI Can cover Voltage, Current, PF, kw, kvar, kva etc. They are interpreted & displayed in the BCS 18

19 Logged Parameters Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions These are based on tariff type programmed to meter These are packets of information on billing parameters like energy, MD etc. for each billing cycle They are also interpreted & displayed in the BCS 19

20 Logged Parameters Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions They are periodic interval-wise information, intervals known as SIP SIP is typically ½ hour for consumer meters & ¼ hour for boundary meters Generally average values of kwh, kvarh, kvah, frequency, PF, Voltages, Currents, Power Down Time etc. 20

21 Logged Parameters Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions These are simply illogical electrical events as seen by meter The correct way is to refer to them as events and not tampers Modern meters have 3 types of tamper related features They are never a No meter can be called conclusive proof that a tamper proof meter consumer has tampered Tamper proof features Tamper deterrent features Tamper evident features 21

22 Logged Parameters Capacity to log parameters is a key feature of electronic meters Logged parameters can be categorized as Instantaneous parameters Billing information Load survey Events or tampers Transactions They are interchange of information between meter & MRI They include change of tariff programme in meter, definition of kvarh & kvah, resetting MD, changing date/time etc. 22
