Seminar presentation on Smart Energy Meter
- 1. PRESENTED BY:- NAME:-MANAS BEURA (DEPT. OF ELECTRICAL ENGG.) REGD. NO.-1401109318
- 2. CONTENTS • Introduction • Types of energy meter • Smart energy meter • Components • Two way communication • Sensing unit • IC and Micro-Controller • Wiring of energy meter • Advantage • Conclusion
- 3. INTRODUCTION The Smart Energy Meter is the future energy meter that will help us for managing our energy use . It itself can’t save energy but it can give us a visualization of energy that we are using at any instant of time. This may lead us to save energy, which is the demand of the present generation.

- 20. CONCLUSION Smart energy meter is an advanced electric meter that identifies consumption in more detail than a conventional meter and optionally communicates that information via some network system back to the distribution company and user for monitoring and billing purpose. Smart energy meters are often combined with modern communication technologies thus enabling cost effective mode of meter reading. It curbs power theft, improves regulation and allows transparency enhancement. The core benefits of smart energy meters can be fully realized with proper installation and timely updating of newer technologies.
