CTO of "Elgama-Elektronika" Dr Nerijus Kruopis was interviewed by www.Smart-Grids.pl. In the article Dr N.Kruopis shared his experience about Leveraging IoT, PLC, and customization to deliver high-class products. https://lnkd.in/dRrFqbV
Elgama-Elektronika is present on the electricity metering market already more than 27 years. Since 1992, with headquarters located in Vilnius (Lithuania), the company develops and produces static electricity meters, as well as solutions for smart metering. Polish electricity utilities have been already familiar with GAMA 100 single-phase and GAMA300 three-phase series of meters, that had been delivered to Polish market of residential and industrial electricity metering. Just last year (in 2018) a new type G3G balance electricity meters were installed on transformer substations in Poland. Elgama-Elektronika has supplied about 16’000 pcs of those meters in total. Meters have been designed for Polish market under the contract with three utilities Tauron, PGE and Innogy. Polish utilities have compiled joint requirements for balance meters and have carried out combined public procurement process. The requirements comprised not only “traditional” functionality of sub-station meters of accuracy class 0.5s, but also included strong emphasis on measurement of power quality parameters. Meters were requested to measure the following voltage quality indicators according to EN 61000-4-30 (class B) standard: slow variation, total harmonic distortion (THD), unbalance and flicker. High speed Ethernet interface is used to read out metering data automatically from meters to the Central System (server). Meters compile weekly reports on power quality, comprising profile of quality indicators, as well as log book of voltage variations, that exceed the configured limits. Since this approach was quite novel for balance meters, according to the public procurement procedure meters had to pass extensive testing session in Tauron utility laboratory (in Tarnow), as well as in AGH electricity energy laboratory (in Krakow), where power quality measurements were tested. Successful test results opened the way for G3G meters to Polish market, and today utilities have already one-year experience in automated measurement of power quality parameters at transformer substations.
