The concept of an electrically short, medium , and long line is primarily based on the
Nominal voltage of the line
Physical length of the line
Wavelength of the line
Power transmitted over the line
Answer: Option B.
The concept of electrically short, medium and long line is primarily based on the physical length of the line.
Keeping in view the cost and overall effectiveness, which of the following circuit breakers is best suited for capacitor bank switching?
Answer: Option A.
Because of short gal and excellent recovery characteristics of vacuum breakers they can be used where the switching frequency is high and required to be reliable and maintenance required is also least. Hence, suitable for capacitor bank switching.
Feedback control systems are
Insensitive to both forward and feedback path parameter changes
Less sensitive to feedback path parameter changes than to forward path parameter changes
Less sensitive to forward path parameter changes than to feedback path parameter changes
Equally sensitive to forward and feedback path parameter changes.
