Power Transmitted Using Load Current(Two-Wire Mid-Point Earthed) Formula:
| From: | To: |
Power Transmitted Using Load Current(Two-Wire Mid-Point Earthed) is defined as the product of current and voltage phasor in a overhead dc line at the receiving end. This calculation is essential for determining the power being transmitted through a two-wire system with mid-point earthing.
The calculator uses the formula:
Where:
Explanation: The formula calculates the power transmitted by multiplying the current by twice the maximum voltage, accounting for the two-wire mid-point earthed configuration.
Details: Accurate power transmission calculation is crucial for designing efficient electrical transmission systems, ensuring proper load management, and maintaining system stability in overhead DC lines.
Tips: Enter current in Amperes and maximum voltage in Volts. All values must be valid positive numbers greater than zero.
Q1: Why multiply by 2 in the formula?
A: The multiplication by 2 accounts for the two-wire configuration with mid-point earthing in the power transmission system.
Q2: What are typical values for overhead DC systems?
A: Typical values vary based on system design, but current can range from amps to kiloamps, and voltage from volts to kilovolts depending on the application.
Q3: When should this calculation be used?
A: This calculation is specifically designed for two-wire mid-point earthed overhead DC transmission systems to determine the power being transmitted.
Q4: Are there limitations to this formula?
A: This formula assumes ideal conditions and may need adjustments for factors like line resistance, temperature effects, and system losses in practical applications.
Q5: How does mid-point earthing affect power transmission?
A: Mid-point earthing provides a reference point that helps maintain voltage stability and can improve system safety in two-wire DC transmission systems.
