The Technical Company for Electrical Engineering (TCEE) in Palestine, has launched a pilot project in the village of Rummanah to introduce an intelligent split-system for electricity metering based on ADDAX technology.
Unauthorized connection and theft of electricity is a serious problem for Palestinian energy companies. Electromechanical meters,as well as modern electronic meters,can’t track the location of the theft of electricity and prevent losses,so it was decided to launch a pilot project for the introduction of an intelligent ADDAX IMS accounting system developed by ADD GRUP. A similar project was recently launched in the Hungarian electric grid E.ON.
The first smart meters were installed in the village of Rummanah, located 17 km north-west of the city of Jenin. There were connected: 850 single-phase pole meters, 50 three-phase meters, 25 three-phase transformer meters, 6 data concentrators, AMI system and a vending station based on STS.
The main focus of the pilot project was on single-phase pole meters, which were installed on a pole or fixed to wires above the ground without any box. Such an installation is safe for streets and can withstand extreme weather conditions (rain, direct sunlight, dust or sand storms). One of the main advantages of the design is that the meter itself is inaccessible to outsiders and the possibility of illegal access is close to zero.
An effective tool to avoid the accumulation of consumer debt to the supplier is the installation of a prepayment system based on the STS standard. For this purpose, a vending station was established where you can buy tokens (20-digit numeric codes that allow you to load a certain amount of kWh) and refill your account. The consumer can enter a 20-digit code using Consumer Interface keyboard to load the credit into the meter.
Since the first months of work, the pilot project has shown very promising results. The Palestinian company, having analyzed the work of ADD GRUP meters, has identified a number of advantages, among which:
- The ability to remotely connect and disconnect consumers, this reduces costs and saves time.
- The ability to calculate power losses by a transformer.
- The ability to detect problems and fix them as soon as possible.
- The ability to load the profile and monitor the load of consumption for a certain period of time, from 5 minutes to 24 hours, this allows you to get an accurate picture of energy losses.
- The ability to reduce the load of the transformer by obtaining data for each feeders.
The energy company also noted the attractive design and compactness of the meters, which are very convenient for installation and use, as well as saving on the boxes for meters that are not needed in case of using pole meter that can withstand extreme weather conditions.
The project has become a good start for the promotion of smart meters ADD GRUP in the electricity market of Palestine. Several municipal networks of the country have already placed orders for the commercial implementation of ADDAX split solutions. In the future, it is planned to implement new projects, which will take into account all the wishes and proposals of our partners and develop the best and most advanced solutions.
