Enter the maximum deviation from the average current and the average current into the calculator to determine the current imbalance.

Current Imbalance Formula

The following equation is used to calculate the Current Imbalance.

CI= Imd / Iave * 100
  • Where CI is the current imbalance percentage
  • Imd is the maximum deviation from the average current (amps)
  • Iave is the average current (amps)

To calculate a current imbalance, divide the maximum deviation from the average current by the average current, then multiply by 100.

What is Current Imbalance?


A current imbalance is a measure of how steady a currents flow is relative to it’s average current. The greater the maximum deviation of the current from the average, the greater the imbalance.

How to Calculate Current Imbalance?

Example Problem:

The following example outlines the steps and information needed to calculate Current Imbalance.

First, determine the average current. In this system, the average current is measured to be 100 amps.

Next, determine the maximum deviation from the average. The maximum current deviation for this system is measured to be 22.5 amps.

Finally, calculate the current imbalance using the formula above:

CI % = Imd / Iave * 100

CI % = 22.5/100 * 100

CI % = 22.5%
