Correct Answer - Option 2 : 5%
Concept:
The voltage regulation of a generator is defined as the change in the voltage drop from no load to full load to full load voltage.
Voltage regulation = (no-load voltage - full load voltage)/full load voltage
Calculation:
No load voltage = 210 V
Full load voltage = 200 V
Voltage regulation = (210 – 200)/200 = 0.05 = 5%
Important Points:
- During on-load conditions, a differentially compounded DC generator has the poorest voltage regulation.
- During the no-load condition, the DC series generator has the poorest voltage regulation.
