Performance testing and reliablity of 2 pole magnetic latching relays for smart meters

摘要

This is Magnetic latching relay play a very important role in the implementation of the smart meters. These relays have low energy consumption, low cost compared to 2 single pole latching relays and are widely used in smart meters. The performance and quality of the meters are based on magnetic latching relays. This paper discusses the different steps involved in performance testing and Reliability of 2 Pole Magnetic latching relays. Two Pole latching relays replace the 2 single pole latching relays so it increases the reliability and decreases the complexity of the smart meter. A number of magnetic relay samples have been tested and the outcome says the large current can cause the damage to the relays. In this paper we will discuss different tests which are conducted on latching relays which improve the quality of the smart meters. The regulatory and IEC standard all metering and latching relay companies has to follow is IEC 62055-31.
