Abstract

Smart Meter is one of the most significant devices of the smart grid. It is an AC static watt-hour meter with time-use registers and internal connect and disconnect switches with two-way communication. Conventional static meters are being replaced with smart meters to reduce Aggregate Technical and commercial (AT and C) losses and improve the quality, reliability and affordability of power supply which is the main objective of the Revamped Distribution Sector Scheme (RDSS). To ensure the reliability of smart meters, they have to be tested under various influence quantities in testing laboratories as per National/International standards before being installed in the field. The Standards stipulate various test conditions to which the Smart Meters are to be subjected to ensure their withstanding capacity and accuracy. During the type test, it is observed that a few meters fail to withstand such simulated conditions. This paper presents the performance of smart meters during metrological tests as per Indian standards.
