Active AMR systems
I. Global data reading system in Lithuania (Utilities)
In 2002 were started implementation works of global Lithuanian data reading system in "Lietuvos energija", "RST" and "VST" utilities. For such system "Elgama-Elektronika" electricity meters (EPQS, EPQM, EMS), "Elgama Sistemos" controllers (MDC) and "Sigmatelas" software were used. Now about 30.000 electricity meters installed in transformer stations and main power plants are connected to this system and the data is read every 15 minutes using GPRS and LAN technologies. This system is the foundation for formation of the electric power market in Lithuania and realization of the possibility of hourly-based trade.

II. Automated data reading system in ОАО "АЭК КОМИЭНЕРГО", Russia (Utilities)
JSC "Sigmatelas" using our multifunctional electricity meters EPQS installed automated data reading and billing system in ОАО "АЭК КОМИЭНЕРГО", Russia. Four AMR systems were implemented in different power stations and all those systems were linked together in this project. System consists of 149 nos. electricity meters EPQS, SICON controllers and software EMCOS-Corporate and EMCOS Local. The entire project is designed to manage and account consumption (generation) of the energy (demand) of ОАО "АЭК КОМИЭНЕРГО" objects, moreover, to measure and provide constant monitoring of the electric power quality.

III. Apartment building in Kaunas, Lithuania (Residential)
In 2006 complete residential electricity meter reading and billing system project in Kaunas was fulfilled using' Current loop electrical interfaces and LAN/internet technology. The system is installed in one 12-floor apartment building and consists of: 91 electronic three-phase meters EMS, MCL 4.0 controller, 6 expanders CLCL 4.2 and software ENERSIS NG (see picture below). Meters are installed in stair landings, expanders in 1st, 4th and 8th floors, and controller in 1st floor. Every current loop interface links four meters, up to 16 meters to one expander. Data is collected to administrator PC through Internet and billing information is sent to every consumer at the beginning of the month. Administrator not only prepares billing information, but also may analyze load profiles and other important data.
