1. What is Single Phase Line Voltage?

Single phase line voltage refers to the voltage measured between any two lines in a single-phase electrical system. In a single-phase system, the line voltage equals the phase voltage.

2. How Does the Calculator Work?

The calculator uses the single phase line formula:

Where:

• \( V_{line} \) — Line voltage (V)
• \( V_{phase} \) — Phase voltage (V)

Explanation: In single-phase systems, the voltage between any two lines is equal to the phase voltage.

3. Importance of Line Voltage Calculation

Details: Accurate line voltage calculation is crucial for electrical system design, equipment selection, and ensuring proper operation of electrical devices.

4. Using the Calculator

Tips: Enter phase voltage in volts. The value must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between line voltage and phase voltage?
A: Line voltage is the voltage between any two lines, while phase voltage is the voltage between any line and neutral.

Q2: Does this calculation apply to three-phase systems?
A: No, this calculation is specific to single-phase systems. Three-phase systems have different relationships between line and phase voltages.

Q3: What are typical single-phase voltage values?
A: Common single-phase voltages include 120V, 230V, and 240V, depending on the country and application.

Q4: Why is accurate voltage calculation important?
A: Proper voltage calculation ensures electrical equipment operates within specified limits and prevents damage or inefficient operation.

Q5: Can this calculator be used for AC and DC systems?
A: The relationship V_line = V_phase applies to both AC and DC single-phase systems.
