    The Electricity Meter Test System is used for testing of all types of electricity meters on-site or in a laboratory: single- or three-phase, mechanical or electronic, direct or indirect.  It consists of two units:

    • Unit 1: EE-120A-3S-C – Three-Phase Current Load to 120 A (20 A) &  Energy Standard class 0.04 or 0.02 in one case;
    • Unit 2: EE-500V-3 (Option) – Three-Phase Voltage Generator up to 500 Vac controlled from Unit 1 via RS485.

    TESTS: Error, Register, No Load and Starting Current Test;

    ENERGY TYPE: Active, Reactive or Apparent energy; 

    MEASUREMENT MODES: Test Plans, Manual Tests, Load Only;

    ANALYSIS MODE: Performed with Current Clamps to 100 A (1000 A); 

    MEMORY: Max. 100 Files, with 48 test points each, are saved in Flash; 

    SOFTWARE: EE Software operates under Windows with the following main functions: Control of the Test System, Download Files, Search in MySQL Data Base, Print Test Reports, Export in Excel, Create Test Plans.



    • Flexible structure: EE Test System works in 4 different modes, with or without the Voltage Generator:
      • EE-120A-3S unit is used only as a Standard for Calibration or Analysis of the customer load, meter and CT testing
      • EE-120A-3S unit is used for on-site Meter tests, generating current synchronized with the service voltage
      • EE-120A-3S and EE-500V-3 units are used together to test the Meter with generated current and voltage;
      • Load Mode – generation of load values and indication of Vector Diagram or a Table with the values of U, I, P, ϕ, PF, THD, f
    • PC Control: The EE Test System can be controlled from a PC, using EE Software for testing the meter
    • Automatic Test Plans: Test Plans are used to perform Meter tests automatically, with or without PC
    • Export of Test Reports in Excel.
    • Statistics (New!): Up to 5 Errors at one Test Point are repeated, the Average Error and Standard Deviation are calculated
    • Generation of harmonics – up to 19th harmonic, with or without the need of a PC
