1. What is Maximum Voltage using Load Current (Two-Phase Three-Wire OS)?

Maximum Voltage using Load Current (Two-Phase Three-Wire OS) refers to the peak voltage level in a two-phase three-wire overhead system, calculated based on the power transmitted, phase difference, and current flowing through the system.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_m = \frac{P}{\sqrt{2} \cdot \cos(\Phi) \cdot I} \]

Where:

\( V_m \) — Maximum Voltage Overhead AC (Volt)
\( P \) — Power Transmitted (Watt)
\( \Phi \) — Phase Difference (Radian)
\( I \) — Current Overhead AC (Ampere)

Explanation: This formula calculates the maximum voltage by considering the power transmitted, the cosine of the phase difference (power factor), and the current in the system.

3. Importance of Maximum Voltage Calculation

Details: Calculating maximum voltage is crucial for designing and maintaining overhead power systems, ensuring proper insulation, and preventing equipment damage due to overvoltage conditions.

4. Using the Calculator

Tips: Enter power transmitted in watts, phase difference in radians, and current in amperes. All values must be positive and valid for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why is the square root of 2 used in the formula?
A: The square root of 2 factor converts RMS values to peak values in AC systems, as maximum voltage is the peak voltage in the waveform.

Q2: What is the significance of phase difference in this calculation?
A: Phase difference (power factor) affects the real power component and is essential for accurate voltage calculation in AC systems.

Q3: Can this formula be used for single-phase systems?
A: This specific formula is designed for two-phase three-wire systems. Single-phase systems use different voltage calculation methods.

Q4: What are typical values for maximum voltage in overhead systems?
A: Maximum voltage values vary based on system design and regulations, but typically range from hundreds to thousands of volts depending on the application.

Q5: How does current affect the maximum voltage calculation?
A: Higher current values typically result in lower maximum voltage calculations for a given power level, following the inverse relationship in the formula.
