Electricity Information Integrated Management Automation System (IMAS) is an efficient, economical and reliable All-In-One solution for automatic meter reading (AMR) and management.

Integrate electricity power level of:
    - High voltage (HV) metering for substations
    - Middle voltage (MV) metering for C&I (Large-Scale) Consumers /Distribution Transformers (DT)
    - Low voltage (LV) metering for residential

Integrate business applications of:
    - Data management
    - Report & graph analysis
    - Event alarm
    - Line loss analysis

Integrate database interface with:
    - Management Information System (MIS)
    - Customer Information/Service System (CIS)
    - Billing System
    
System Functions:

    - Data acquisition: KWH / KW / KVAR / Voltage / Current / Demand / PF / Phase Angle / Frequency, etc.
    - Automatic calculation & statistics: Statistics of raw data, line loss data, etc.
    - Working condition monitor & analysis: Power quality supervision, line loss analysis, power load analysis, meter status, etc.
    - Event log & alarm: Support more than 60 kinds of abnormities record and send SMS to duty person. (need local mobile network support) E.g.: Voltage loss, open phase, reversed phase, abnormal CT status, network failure, hardware failure, electricity tampering, etc.
    - Load control: Automatic/manual switch on/off. Can be controlled by demand/energy threshold.
    - Report forms, graph & curves
    - WEB service: Users can access to HL3000-WEB from anywhere has internet connection
    - Save data as other format: Support save data as MS Excel®/PDF/TXT(CSV)/XML format from HL3000-WEB or HL3000 server
    - Real-time time synchronizing.

System Features:

    - Database sharing: Interface with other applications (MIS/EMS/SCADA/SAP®)
    - Live updates and remote meter settings via mobile network
    - Smart communication: Can be self-adapted with any GSM/GPRS/CDMA network
PLC/Zigbee for residential
    - Consideration of stability and reliability
--------1) Distributed network system structure 
---------2) Redundant as dual machines dual networks clusters, dual server hot backup, double machines mutual backup, disc array mode, etc.

    - Universal hardware platform: Users can select hardware equipments like of the brand they are familiar with.
    - High security of system and data processing at 4 levels.

Performance Parameter: 

    - System capacity: Number of terminals ≥30000, number of metering points ≥50000. Data volume is restricted by hard disc capacity in principle
    - System clock error: < 0.1 s;
    - Master station and terminal clock error < 0.5 s;
    - Data precision: equal to the precision of meter reading data;
    - System normal communications can be guaranteed when communications error rate is less than 10-4;
    - System serviceability: 99.9%;
    - System mean time between failures (MTBF) ≥20000h
