Automated intelligent device for managing electronic meter tests for calibration using artificial intelligence techniques

This article deals with the development of an intelligent calibration device for three-phase electricity meters (semi-automatic) that complies with INMETRO and ANNEL calibration standards. The aim of the article was to reduce the measurement error to a certain range. This error is due to the tolerances and uncertainties of the electronic components that make up the printed circuit board of the three-phase electronic meter. The materials and methods used were: HMI Software, Electronic Equipment: Alternating Current (AC) Generator, Alternating Voltage (Vrms) Generator and Voltage and Current Analyser; Pneumatic Actuators, Meters under Test, Control System, using a Proportional, Integral and Derivative (PID) controller. The results achieved were: Test 1: Voltage Signal Quality, Test 2: Current Signal Quality, Test 3: Phase Angle Verification, Test 4: DHT (Total Harmonic Distortion) Verification, Validation and verification of the post-calibration error, finally the results were expressive, since it really validated the automated intelligent device capable of managing the testing of electronic meters for calibration using artificial intelligence techniques on the shop floor.
