Unlocking Reliable Transformer Operation with Accurate K-Factor Analysis
This white paper explores the impact of nonlinear loads and harmonics on transformer heating, emphasizing the importance of K-factor as a metric for transformer sizing and protection. It details the calculation of K-factor, its relationship to harmonic content, and best practices for measurement and analysis using ProVision software. Practical tips are provided to ensure accurate readings and prevent premature transformer failure due to excessive heating.
Key topics include:
- Understanding K-Factor and Its Calculation
- Effects of Harmonics on Transformer Performance
- Best Practices for K-Factor Measurement
- Analyzing K-Factor with ProVision
Why utilities should care:
Accurate K-factor analysis enables improved transformer sizing, reduces risk of overheating, and extends equipment life by accounting for harmonic-induced heating. Proactive monitoring minimizes unplanned outages and supports reliable power delivery during load changes or expansions.
