The modernization of electrical systems has created a growing demand for more accurate, reliable, and integrated measurements within automation and energy management processes. In this context, multifunction electronic meters have become essential in utilities, industries, substations, and control centers, requiring calibration and verification procedures that are increasingly efficient and traceable.
To meet this need, Conprove developed Meter Software, a comprehensive solution for automating energy meter testing, delivering greater productivity, repeatability, and reliability in testing procedures.
Automation Applied to Energy Metering
Meter Software was designed to perform automatic testing on various types of energy meters, simplifying procedures that traditionally required significant operational time and manual intervention.
The solution supports testing of three-wire and four-wire multifunction meters, covering different electrical quantities, including:
- Watt-hour (Wh)
- Var-hour (VArh)
- VA-hour (VAh)
- Q-hour (Qh)
- V²-hour
- I²-hour
- V-hour
- I-hour
This allows laboratories, utilities, and maintenance teams to standardize testing processes and significantly reduce operational errors.
Flexible Configuration for Different Applications
One of Meter Software’s main advantages is its testing flexibility.
Users can configure:
- Export angle
- Power flow direction
- Analyzed quadrant
- Meter class
- Pulse/revolution settings for electromechanical meters
- Maximum creep time
- Stabilization time
- Maximum current
- Specific meter constants
The software also allows users to define which generation channels will be used for voltage and current outputs, enabling adaptation to different applications and test equipment.
Another important feature is the use of reference tables for generation error correction, providing greater accuracy and compliance with calibration requirements.
Available Tests
Meter Software includes a wide range of automated testing functions:
Load Test
Evaluates meter performance under normal operating conditions, verifying accuracy and operational behavior.
No-Load Test
Validates meter behavior in the absence of load current.
Mechanism Test
Verifies the proper operation of internal measurement mechanisms.
Injection Test
Simulates different electrical conditions for operational validation.
Creep Test
Evaluates potential unwanted energy registration when no load is present.
During all tests, the software provides real-time visualization of:
- Waveforms
- Phasors
- Harmonics
These features significantly enhance technical analysis capabilities during testing.
Compliance with Technical Standards
Meter Software includes pre-configured standards, simplifying standardized testing procedures and reducing setup time.
Available standards include:
- INMETRO 587
- INMETRO 587-VAR I
This functionality improves regulatory compliance and testing traceability.
Greater Efficiency and Reliability
Automating calibration and verification processes provides important benefits:
- Reduced testing time
- Standardized procedures
- Minimized human errors
- Greater result repeatability
- Improved technical traceability
- Increased operational productivity
As the electrical sector continues to digitalize, automated solutions become essential to ensure quality, accuracy, and reliability in energy metering processes.
