Download Solution PDFConcept:
- Voltage regulation is the ratio of the difference in voltage drop from no load and the full load to the no-load voltage.
- Mathematically, there are two ways to express the voltage regulation:
\(VR = \frac{{{V_{NL}} - {V_{FL}}}}{{{V_{NL}}}}\)
VNL = No-load voltage and
VFL = Full load voltage
- The above formula is normally used in the case of transformers.
- For alternators and power system calculations, the formula used is:
\(VR = \frac{{{V_{NL}} - {V_{FL}}}}{{{V_{FL}}}}\)
Observation:
Ideally for a regulated power supply VNL = VFL
So, the Voltage regulation is:
\(VR = \frac{{{V_{NL}} - {V_{FL}}}}{{{V_{NL}}}}=0\)%
It should be as low as possible for the proper operation of the electrical devices.
