Transformers are highly susceptible to overheating from harmonic currents. The calculation often involves determining the or K-Factor . The Calculation Formula
Total Factor=F1×F2×F3…×FnTotal Factor equals cap F sub 1 cross cap F sub 2 cross cap F sub 3 … cross cap F sub n Key Factors and Variables
: Thinner air is a less effective cooling medium and a poorer insulator.
In this post, we’ll break down what derating is, why it matters, and how to perform a basic derating calculation.
You must apply both factors to the base rating.
The culprit isn’t bad manufacturing; it’s likely a failure to understand .
