1. What is Line Losses Using Resistance (DC Three-Wire US) Calculator?

The Line Losses Using Resistance (DC Three-Wire US) Calculator estimates the power losses in a DC three-wire underground transmission system based on transmitted power, line resistance, and maximum voltage. It helps in evaluating the efficiency of power transmission.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Line Losses} = \frac{2 \times (\text{Power Transmitted})^2 \times \text{Resistance underground DC}}{(\text{Maximum Voltage})^2} \]

Where:

\( \text{Power Transmitted} \) — Power being transmitted through the line (Watt)
\( \text{Resistance underground DC} \) — Resistance of the underground DC line (Ohm)
\( \text{Maximum Voltage} \) — Maximum operating voltage of the system (Volt)

Explanation: The formula calculates power losses due to resistance in a DC three-wire system, where losses are proportional to the square of the transmitted power and the resistance, and inversely proportional to the square of the voltage.

3. Importance of Line Losses Calculation

Details: Calculating line losses is essential for designing efficient power transmission systems, minimizing energy waste, and ensuring optimal performance of electrical networks.

4. Using the Calculator

Tips: Enter the power transmitted in watts, resistance in ohms, and maximum voltage in volts. All values must be positive and non-zero for accurate calculation.
