VSWR on a line is infinite when the far end of the line is perfectly open or perfectly shorted,
i.e. the line is terminated in an impedance of exactly zero or exactly infinite, AND the line
is perfectly lossless.
Under those conditions, the reflection coefficient is 1.0 and the return loss is zero.

What is the limit of infinity over zero?
infinity? Infinity over zero is undefined, or complex infinity depending on numbers you are including in your number system.
How do you write in interval notation x is positive?
Positive: (0, infinity)Nonnegative: [0, infinity)Negative: (-infinity, 0)Nonpositive (-infinity, 0]
What number is more than infinity?
There is no number greater than infinity. Infinity is defined to be greater than any number, so there can not be two numbers, both infinity, that are different.However, when dealing with limits, one can approach a non-infinite value for a function involving infinity. Take, for example, 2x divided by x, when x is infinity. That value is indeterminate, because infinity divided by infinity is defined as indeterminate, and 2 times infinity is still infinity.But, if you look at the limit of 2x divided by x, as x approaches infinity, you do get a value, and that value is 2. This does not mean that 2x when x is infinity is twice infinity, it just means that, right before x becomes infinity, the ratio is right before 2.Infinity should not be thought of as a number, but rather as a direction. Whereas a number represents a specific quantity, infinity does not define given quantity. (If you started counting really fast for billions of years, you would never get to infinity.) There are, however, different "sizes of infinity." Aleph-null, for example, is the infinity that describes the size of the natural numbers (0,1,2,3,4....) The infinity that describes the size of the real numbers is much larger than aleph-null, for between any two natural numbers, there are infinite real numbers.Anyway, to improve upon the answer above, it is not meaningful to say "when x is infinity," because, as explained above, no number can "be" infinity. A number can approach infinity, that is to say, get larger and larger and larger, but it will never get there. Because infinity is not a number, there is no point in asking what number is more than infinity.
What is infinity times infinity?
INFINITY
What is infinity divided by pi?
Impossible to answer ! Infinity is a never ending quantity - and Pi is a never ending decimal !
If a transmission line is terminated in an open circuit the vswr?
VSWR=Zo-ZL/Z0+ZL since open circuited ZL=infinity so VSWR=infinity
What are the three case in which vswr is infinity?
open circuit load2. short circuit load 3. a purely reactive load.
What is vswr?
VSWR is a ratio which represent the efficient performance in a radio emittion.
What is the reflection coefficient with respct to VSWR?
The reflection coefficient is related to Voltage Standing Wave Ratio (VSWR) as follows: Reflection coefficient = (VSWR - 1) / (VSWR + 1) The reflection coefficient provides a measure of the strength of the reflected wave compared to the incident wave in a transmission line system.
What is vswr range?
1.25:1
Ideal value of vswr?
1 (one)
What is the derivative of infinity?
Infinity is not defined in exact terms, so there's no sense of diff. & intg. It, but if it is to be taken as constant that we have, infinity + 1 = infinity, it should be zero then, but it isnt practical..
What is the VSWR and reflection coefficient?
VSWR = voltage standing wave ratio = ratio of the maximum voltage to minimum on a line = VSWR = Emax / Emin = Imax / Imin Reflection Coefficient is the ratio of reflected voltage to incident voltage. = ZL - ZO / ZL + ZO
What is the ideal value of vswr?
The ideal value of VSWR is 1:1, which indicates a perfect match between the transmission line and the load. A VSWR of 1:1 means that all the power from the source is being transferred to the load without any reflections.
Measurement of vswr using microwave bench set up?
To measure VSWR (Voltage Standing Wave Ratio) using a microwave bench setup, you would typically use a vector network analyzer (VNA). Connect the device under test to the VNA and measure the magnitude of the reflected and incident waves. The VSWR is then calculated as the ratio of these two values.
For a open circuit the VSWR is?
the voltage standing wave ratio is defined (1+p)/(1-p), where p is the the reflection coefficient magnitude. p = 1 for an open circuit, therefore the VSWR will approach infinite.
Can a meggar tester be use to measure voltage standing wave ratio in a feeder cable?
No, a megger tester cannot measure voltage standing wave ratio (VSWR) in a feeder cable. A VSWR meter or network analyzer is typically used to measure VSWR, which is a way to characterize impedance matching in transmission lines. Megger testers are used to measure insulation resistance and continuity in electrical circuits.
