The inertia constant H of a synchronous condenser is
A. greater than that of turbo alternator.
B. greater than that of hydro generator.
C. equal to that of the effective length of the line.
D. none of these.
Answer: D
Share your understanding of this question with the correct explanation.
The answer is D. none of these.
The inertia constant of a synchronous condenser is typically much smaller than that of a turbo alternator or hydro generator. This is because synchronous condensers are not designed to provide mechanical power, but rather to provide reactive power. As a result, they do not need to have as much mass as a turbo alternator or hydro generator.
The effective length of a line is a measure of the resistance and inductance of the line. It is not directly related to the inertia of the line.
Therefore, the inertia constant of a synchronous condenser is not equal to that of a turbo alternator, hydro generator, or effective length of a line.
