1. What is Parallel Circuit Voltage?

In a parallel circuit, the voltage across all components is the same. When connecting generators in parallel, their voltages must be equal to prevent circulating currents.

2. How Does the Calculator Work?

The calculator verifies parallel connection requirements:

Where:

• \( V_{total} \) — Total circuit voltage
• \( V_1, V_2, V_n \) — Individual generator voltages

Explanation: For proper parallel operation, all generator voltages must be equal. The calculator checks this condition.

3. Importance of Voltage Calculation

Details: Correct voltage matching is essential to prevent damage to generators and ensure stable power output in parallel configurations.

4. Using the Calculator

Tips: Enter the voltage of each generator in volts (V). The calculator will verify if they can be safely connected in parallel.

5. Frequently Asked Questions (FAQ)

Q1: Why must voltages be equal in parallel?
A: Unequal voltages cause circulating currents between generators, leading to inefficiency and potential damage.

Q2: What's the tolerance for voltage differences?
A: Typically less than 0.5% difference is acceptable for most applications.

Q3: Can I connect generators with different ratings?
A: Only if their voltages match exactly and their control systems support parallel operation.

Q4: What other factors matter for parallel operation?
A: Frequency, phase sequence, and phase angle must also be synchronized.

Q5: What happens if I connect unequal voltages?
A: Excessive current will flow between generators, potentially tripping breakers or causing damage.
