The Incident Voltage on a transmission line with short circuit termination is equal to half of the Transmitted Voltage. This relationship is fundamental in transmission line theory and wave propagation analysis.
The calculator uses the formula:
Where:
Explanation: For a short-circuited transmission line, the incident voltage wave is exactly half of the transmitted voltage wave due to the reflection characteristics at the short circuit termination.
Details: Accurate calculation of incident voltage is crucial for transmission line design, impedance matching, power system protection, and understanding wave behavior in short-circuit conditions.
Tips: Enter the transmitted voltage value in volts. The value must be positive and greater than zero for valid calculation.
Q1: Why is incident voltage half of transmitted voltage in short circuit condition?
A: In short circuit termination, the reflection coefficient is -1, causing complete reflection with phase reversal, resulting in the incident voltage being half of the transmitted voltage.
Q2: Does this formula apply to all transmission line types?
A: This relationship holds true for lossless transmission lines with short circuit termination at the receiving end.
Q3: What are practical applications of this calculation?
A: This calculation is essential in power system fault analysis, transmission line protection schemes, and high-frequency circuit design.
Q4: Are there limitations to this formula?
A: This formula assumes ideal short circuit conditions and may need modification for real-world scenarios with line losses and imperfect terminations.
Q5: How does this relate to standing wave patterns?
A: The voltage standing wave ratio (VSWR) becomes infinite for short circuit termination, with minimum voltage at the short circuit end and maximum at λ/4 from the end.
