Reflected Current is defined as the current wave that is traveling from the receiving end to the sending end of the Transmission line during transient condition.
The calculator uses the formula:
Where:
Explanation: The negative sign indicates that the reflected current wave is 180 degrees out of phase with the incident current wave.
Details: Calculating reflected current is crucial for analyzing transient conditions in transmission lines, determining wave behavior, and designing proper protection systems.
Tips: Enter the incident current value in Amperes. The calculator will compute the reflected current with opposite polarity.
Q1: Why is the reflected current negative?
A: The negative sign indicates that the reflected current wave is 180 degrees out of phase with the incident current wave, representing the wave inversion upon reflection.
Q2: When does this formula apply?
A: This formula applies during transient conditions in transmission lines, particularly when analyzing wave propagation and reflection phenomena.
Q3: What are typical values for incident current?
A: Incident current values vary widely depending on the system voltage, fault conditions, and transmission line characteristics.
Q4: Are there limitations to this formula?
A: This is a simplified formula that assumes ideal conditions. Actual reflected currents may be affected by line impedance, termination conditions, and other factors.
Q5: How is this used in power system protection?
A: Understanding current reflection helps in designing protection schemes, analyzing fault conditions, and ensuring system stability during transients.
