What effects are produced by change in voltage? 1. Iron los..........varies approximately as V². 2. Cu loss..........it also varies as V² but decreases with an increase in voltage if constant kVA output is assumed. 3. Efficiency...........for distribution transformers, efficiency at fractional loads decreases with in- crease in voltage while at full load or overload it increases with increase in voltage and vice- versa. 4. Regulation..........it varies as but decreases with increase in voltage if constant kVA output is assumed. 5. Heating.........for constant kVA output, iron temperatures increase whereas Cu temperatures decrease with increase in voltages and vice-versa.
