Course overview
Single- and poly-phase metering are the two types of revenue data meters used in the modern world. Technology advances change the designs of meters that may be applied at the service entrance. Still, the purpose, data, and terminology data remain the same. Understanding this information better prepares a technician to service meters today and tomorrow.
The Single- and Poly-phase Metering training course describes the process for meter reading, testing, and calibration. This online course discusses:
- Watt-hour meter purpose and operation
- Meter types
- Understanding meter constants
- Poly-phase circuit metering
- Meter reading, testing, and calibration
- Rotating standard guidelines
Single- and Poly-phase Metering is part of the Distribution Systems training series.
