Meter Test Bench with 5 Positions

TST 3/5 Universal

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
