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
Advantages
- 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
