Ami Automatic Meter With TOU Step Tariff

Three Phase Smart Meter with with TOU and step tariff functions
 
General introduction
Three Phase Smart Meter with TOU and step tariff functions can measure import and export active energy,inductive and capacitive reactive energy, with TOU and step tariff functions, and can be optional with PLC or RF module. It can be controlled to disconnect and reconnect the load remotely.
Main Function
1. Display and indication: It adopts a large screen LCD with abundant graphics and hint text. The displayed contents can be scrolled automatically or by button, and the displayed items can be configured as per the requirements. It is with backlight. Meter can be read during power outage.
2. Measurement: It can measure voltage, current, active power, reactive power, apparent power, power factor, import and export active maximum demand, and four quadrant reactive maximum demand. It is with high accuracy. Class 0.2S, Class 0.5S or Class 1 for kWh are available.
3. TOU:4 tariffs; Built-in 2 sets of time zone tables and 2 sets of daily period tables, which can be configured as per the requirements. The switching time for both 2 sets of time zone tables and 2 sets of daily period tables can be set to achieve the mutual switching. It can be set 14 time intervals and 254 holidays.
4. Data snapshot: It supports freezing which include daily freezing, hourly freezing, occasional freezing, immediate freezing.
5. Event logs: It can separately record latest 10 times events, such as power outage, programming, time correction, meter cover open and terminal cover open, disconnection and re-connection, reset of events, reset of meter, etc.
6. Communication interface: The meter has one infrared interface, one RS485 and one PLC or GPRS module interface. Interfaces are independent. The protocol of meter conforms to DL/T645-2007.

Q & A
 
Q1: What is the AMI System? 
 
Advanced Metering Infrastructure (AMI) is the technology of automatically collecting data from energy metering devices and transferring that data to a central database by communication technology for remote control and analyzing. RS801E AMI system is composed of management software, remote communication channel, power management terminal, regional summary meter, local communication channel, user energy meter and other equipments. Power companies can build AMI system to replace the manual meter reading to save human resources, reduce meter reading costs and improve meter reading efficiency and success rate. The AMI system reduces the error rate, the electricity loss and eliminates the false meter reading by personnel. The AMI system also can monitor the status of the users and find the abnormal information to alarm in time. It also collects data from regional summary meter and the regional line loss can be calculated. The software system is developed by Java and it can be deployed on Windows, Unix, and other major operating systems. The system is developed based on Enterprise-class Jave EE standards, a three-tier technical architecture (client / middleware server / database server) as the basis for the system. The system has excellent openness, scalability, flexibility and high reliability. Many advanced computer and communication technologies are used on this AMI system to satisfy the needs of power companies in different environments.
