Grade: 100.00%.

Key Concepts in Transformer Voltage Regulation

Reason for Increased Secondary Voltage:
- Occurs when the load is disconnected.
Voltage Regulation Definition:
- Measures transformer performance between no-load and full-load conditions.
Critical Consideration:
- Voltage regulation is vital for supplying voltage-sensitive loads.
Voltage Regulation Calculation:
- Common formula used:
  - ( V_{\text{REG}} = \frac{(V_{\text{NL}} - V_{\text{FL}})}{V_{\text{NL}}} \times 100 )
- This formula highlights the difference between no-load voltage (NL) and full-load voltage (FL).
