Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A power station uses a Delta-Star transformer to step up voltage from 11 kV to 400 kV for transmission. If the transformer operates at 95% efficiency, determine the power loss due to inefficiencies when transmitting 500 MW.

💡 Hint: Calculate input power based on efficiency.

Challenge 2 Hard

Discuss the implications of using a Δ-Δ transformer instead of a Δ-Y transformer in a system where load balancing is critical. How would this impact grounding and stability?

💡 Hint: Consider what grounding offers in terms of operational stability.
