Meter Engineering Board 3 (MEB3), True Three-Phase Meter Engineering Board for Advanced Meter Performance Validation
The TESCO MEB3 Meter Engineering Board is a true three-phase system designed for advanced validation of meter performance under real-world operating conditions.
With independent phase control and engineering-grade metrology (~0.1% accuracy), the MEB3 enables utilities to analyze meter behavior, load response, and operational performance in complex and polyphase environments.
Description
What is a True Three-Phase Meter Engineering Board?
A true three-phase meter engineering board applies independent voltage and current to each phase, allowing utilities to evaluate meter behavior under realistic operating conditions.
This enables:
- Phase-by-phase validation
- Load and performance analysis
- Advanced functional and engineering testing
Meter Performance Validation Under Load
The MEB3 is designed to evaluate how meters perform under real operating conditions by applying true three-phase voltage and current and running tests over time.
This includes validating:
- Demand performance
- Time-of-use calculations
- Phase relationships and load response
With approximately 0.1% accuracy, the MEB3 provides engineering-level validation to confirm that meter performance is consistent and within expected operating ranges—without requiring revenue-grade calibration.
