    Application and brief description

    The Test Bench consists of the following components:

    • A Three-Phase Voltage Generator EE-500 V for voltages up to 500Vac
    • Five identical Modules EE-120A, each comprising three-phase current generators from 1 mA to 120A each and Energy Standard Class 0.04
    • Meter Suspension Rack with 5 positions for hanging the meter, Scanning Heads, IR Electronic Readers, Error Indicators, Tariffs, Panic Button, Lamp
    • PC with EE Software for control, memorizing, search and print of Reports


    • Meter Tests with closed U-I links, no need of Isolating CTs or VTs
    • Overall Accuracy – ±0.04% or ±0.02%; No additional Error from ICTs or voltage drops
    • If a meter is missing, no need of re-connections, just switch off the Module
    • Very safe, simple, modular construction; easy for mounting, support and calibration
    • The needed output power for the current generator is twice less, compared with conventional Benches, because of the short cables and lack of Isolating CTs
    • Meters with different constant can be tested on each test position
    • Automatic reading of the meter registers with IR Head, according to IEC 62056-21
    • Export of Test Results in Excel
    • Statistics – up to 10 repeats, calculation of Average Error, Standard Deviation
