ICSE 10th Physics - Problem 8 - Copper loss in transformers

Title: Problem 8 - Copper loss in transformers Copper loss in transformers refers to the energy lost due to the resistance of the windings when current flows through them. It is a variable loss that increases with load and is calculated using the formula. Reducing copper loss improves transformer efficiency significantly. 🔌 What Is Copper Loss in Transformers? Definition • Copper loss is the electrical energy dissipated as heat in the primary and secondary windings of a transformer due to their resistance. • It is also called I²R loss, where: • = current through the winding • = resistance of the winding Formula • Units: Watts (W) • Occurs in: Both primary and secondary windings 📈 Why Copper Loss Is a Variable Loss • Depends on load current: As load increases, current increases, and so does copper loss. • Unlike core loss (iron loss), which is constant regardless of load, copper loss varies dynamically. 🌡️ Temperature Effect on Resistance • Resistance increases with temperature, which increases copper loss. ⚙️ Methods to Reduce Copper Loss • Use high-conductivity copper for windings • Optimize winding design to reduce resistance • Use larger cross-sectional area conductors • Improve cooling to reduce temperature rise • Operate near rated load to avoid excessive current 🔔 Like, Subscribe, and Share!
