Transmitted Current-3 is defined as the current wave that is traveling through the Load-3 of the Transmission line. It represents the electrical current flowing through the tertiary winding in power transmission systems.
The calculator uses the formula:
Where:
Explanation: This formula calculates the current in the tertiary winding based on Ohm's law, where current equals voltage divided by impedance.
Details: Accurate calculation of transmitted current is crucial for designing and analyzing power transmission systems, ensuring proper load distribution, and maintaining system stability and efficiency.
Tips: Enter transmitted voltage in volts and impedance of tertiary winding in ohms. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the significance of tertiary winding in transformers?
A: Tertiary winding provides a path for zero-sequence currents, helps in voltage stabilization, and can be used for auxiliary power supply or reactive power compensation.
Q2: How does impedance affect transmitted current?
A: Higher impedance results in lower transmitted current for a given voltage, following Ohm's law (I = V/Z).
Q3: When is this calculation particularly important?
A: This calculation is critical during power system design, fault analysis, load flow studies, and when determining protective relay settings.
Q4: Are there limitations to this formula?
A: This formula assumes ideal conditions and may need adjustments for factors like temperature variations, frequency dependencies, and non-linear loads.
Q5: How does this relate to overall power system performance?
A: Proper calculation of transmitted currents helps in optimizing power flow, reducing losses, and ensuring the reliability and safety of the power transmission system.
