1. The Smart Meters and Their Role in Reducing Loss by Preventing Tampering and Theft of Electricity Engineer / Hassan Ahmed Al-Hail Qatar Corporation for Electricity and Water

2. Contents Introduction Electromechanical Meters Smart Meters Tampering with Meters Options of Tampering Detection Conclusion

3. Introduction The smart meter is an electrometer that measures electricity consumption by time repetition. The merit of these meters is that they send and receive (information / commands) to and from the main center

4. The Electromechanical Meters Cannot detect or record any tampering attempt. Cannot see any obvious damage save in location

5. The Smart Meters Time-Based Tariff (Multi-tariff). Consumption Statements to Subscriber and Corporation. Net metering. Notice of Current Outage/Restoring Electricity Current Disconnect/Re-Connect Load Determination for Demand Response (DR) Monitoring Electricity Current Quality Detection of Tampering/Theft of Electricity

6. Tampering With Electromechanical Meters Changing connection by opening / closing the lid without any evidence Putting a strong magnet to stop / tamper with the work of the meter. Inserting a metallic object / pin in meter to stop spinning.

7. Tampering With Electromechanical Meters Raising Voltage Terminal. Shortening connections Current (Transformer (CT) Reversing Connection of Current Transformer (CT) single phase / three-phase

8. The Smart Meters All smart meters are shut down by the Corporation Any attempt to change plug in needs opening the meter cover.

9. Tampering Detection Steps Meter sends alert to meter data management (MDM) system which in turn sends orders / alerts to the system operator. Alert appears on the meter screen

10. Opening Lid Leakage Phase Detection in the System

11. Reversing Spinning Electricity Outage Detection in the System

12. Serial Reverse Negative Energy Direction (Reversed Contact) Meter Terminal Removal Detection Detection in Meter Screen

13. Conclusion The Consumer Interest More price and service options and more information to manage consumption and cost and many other decisions. The Corporation Interest Helps avoid estimated readings, and provides accurate bills in a timely manner.
