Ground Strap Inductance Calculator
Grounding straps are used to provide a low-impedance path for electrical currents to flow safely into the ground. This plays a important role to find the effectiveness of grounding systems and prevent unwanted electrical interference and noise. To have the lowest inductance, usually a wide flat strap is used to make the best ground connection. You can read more about it here.
This online calculator helps you calculate the value of inductance for the grounding strap, when you enter the length, width and thickness of the strap.
Formula
\[ StrapInductance = 0.2 * L \left( ln \left(\frac{2 * L}{w + t}\right) + \frac {0.223 (w + t)}{L} + 0.5 \right)\]
where :
- L = Length
- w=Width
- t=Thickness
