Voltage Unblanace Calculator


Calculating voltage imbalance is crucial in maintaining a stable electrical system. A voltage imbalance calculator aids in identifying discrepancies in the distribution of voltages, enabling prompt corrective measures. This article provides a simple yet effective for a voltage imbalance calculator.

How to Use

The calculator is user-friendly. Input the line-to-line voltages (Vab, Vbc, Vca) and click the “Calculate” button. The result will display the percentage voltage imbalance.


The formula for calculating voltage imbalance is as follows:

Example Solve

Suppose we have line-to-line voltages:

  • Vab​=415 V
  • Vbc​=400 V
  • Vca​=410 V

The maximum deviation is max(∣415−408.33∣,∣400−408.33∣,∣410−408.33∣)=7 V.

Now, apply the formula:


Q1: Why is voltage imbalance important to measure?

A1: Voltage imbalance can lead to increased energy consumption, reduced equipment lifespan, and decreased system efficiency.

Q2: What is an acceptable voltage imbalance percentage?

A2: Typically, an imbalance of 2% or less is considered acceptable in most electrical systems.

Q3: Can the calculator handle different voltage units?

A3: No, ensure all input voltages are in the same unit (e.g., volts).


Maintaining balanced voltages is crucial for a healthy electrical system. The provided HTML and JS code for a voltage imbalance calculator offers a convenient way to assess and address potential issues in your power distribution network.
