1. What is Transmitted Current (Line OC)?

Transmitted Current (Line OC) refers to the current wave that travels through the load of a transmission line during open circuit conditions. It is directly related to the incident current wave that travels from the sending end to the receiving end during transient conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Transmitted Current = 2 \times Incident Current \] \[ I_t = 2 \times I_i \]

Where:

\( I_t \) — Transmitted Current (Ampere)
\( I_i \) — Incident Current (Ampere)

Explanation: This formula represents the relationship between incident and transmitted current waves in transmission line theory, specifically under open circuit conditions where the transmitted current is exactly twice the incident current.

3. Importance of Transmitted Current Calculation

Details: Accurate calculation of transmitted current is crucial for analyzing wave propagation in transmission lines, designing protection systems, and understanding transient behavior in electrical networks during fault conditions.

4. Using the Calculator

Tips: Enter the incident current value in Amperes. The value must be a positive number greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is transmitted current twice the incident current?
A: This relationship occurs due to the reflection coefficient being +1 at open circuit ends, causing the transmitted current to be the sum of incident and reflected currents.

Q2: What are typical values for incident current?
A: Incident current values vary widely depending on the system voltage, fault type, and network configuration, ranging from amperes to kiloamperes.

Q3: When is this formula applicable?
A: This formula applies specifically to open circuit conditions in transmission line analysis during transient states.

Q4: Are there limitations to this formula?
A: This formula assumes ideal open circuit conditions and may need modification for real-world scenarios with losses and other practical considerations.

Q5: How does this relate to voltage calculations?
A: While current doubles at open circuit ends, voltage also experiences specific behavior that follows different reflection principles in transmission line theory.
