Streamline Power Analysis with Per-Unit Scaling in ProVision
This white paper demonstrates how per-unit scaling simplifies AC power analysis by normalizing voltage, current, and power values for direct comparison, regardless of differing equipment ratings or transformer ratios. Using ProVision's scale factor feature, users can quickly convert measurements to per-unit values, enabling clearer visualization of system performance, voltage unbalance, and load conditions, even in complex multi-phase environments.
Key topics include:
- Per-Unit Overview
- Using Per-Unit Scaling in ProVision
- Single-Phase Example
- Three-Phase Example
- Voltage Unbalance and Fault Analysis
Why utilities should care:
Per-unit analysis enables clear, normalized comparisons across systems with different nominal voltages, simplifies detection of voltage unbalance and transformer loading issues, and aligns measurements with industry standards, supporting more accurate diagnostics and reporting.
