Leakage Current Formula
The following formula is used to calculate a leakage current.
LC = 377*V*C
- Where LC is the leakage current (amps)
- V is the voltage (volts)
- C is the capacitance (Farads) between line and ground
To calculate the leakage current, multiply the voltage by 377, then multiply the capacitance by the result.
What is a leakage current?
Leakage current is defined as any amount of current traveling along an unwanted path in a circuit.
How to calculate leakage current?
The following example outlines the steps and information needed to calculate leakage current.
First, determine the voltage between line and ground. In this case, the voltage is measured to be 500 volts.
Next, determine the capacitance between line and ground. For this example, the capacitance is 2.5 Farads.
Finally, calculate the leakage current using the formula above:
LC = 377*V*C
LC = 377*500*2.5
LC = 471250 amps
