Question 1
What is the formula for calculating voltage regulation?
- \\( VR = \\frac{V_{2,Full-Load} - V_{2,No-Load}}{V_{2,Full-Load}} \\times 100 \\% \\)
- \\( VR = \\frac{V_{2,No-Load} - V_{2,Full-Load}}{V_{2,No-Load}} \\times 100 \\% \\)
- \\( VR = \\frac{V_{2,Full-Load}}{V_{2,No-Load}} \\times 100 \\% \\)
💡 Hint: Remember to focus on the change in voltage based on loading conditions.
Question 2
True or False: A lower voltage regulation percentage is indicative of poorer transformer performance.
- True
- False
💡 Hint: Consider what areas of performance VR reflects.

Challenge Problems
Push your limits with challenges.
Question 1
A transformer has a no-load voltage of 750V and connects to a load that causes the full-load voltage to drop to 720V. Calculate the voltage regulation and analyze the performance implications.
💡 Hint: Use the voltage regulation formula and consider how this affects usability at full load.
Question 2
Evaluate how different power factor conditions (0.9 lagging vs. 0.9 leading) would affect the voltage regulation of a transformer rated at 600V full load, assuming no-load voltage remains constant at 615V.
💡 Hint: Reflect on how variations in load type influence voltage drops.
