Enter the breakdown voltage and the material thickness into the calculator to determine the dielectric strength of the material.
Dielectric Strength Formula
The following formula is used to calculate the dielectric strength of a material.
DS = BV / T
Variables:
- DS is the dielectric strength (kV/mm)
- BV is the breakdown voltage (kV)
- T is the material thickness (mm)
To calculate the dielectric strength, divide the breakdown voltage by the material thickness.
What is Dielectric Strength?
Dielectric strength is a measure of the electrical strength of a material as an insulator. It is defined as the maximum electric field that a material can withstand under ideal conditions without breaking down and conducting electricity. Dielectric strength is typically expressed in kilovolts per millimeter (kV/mm). It is an important property for materials used in electrical insulation, as it indicates how much electric stress the material can endure before it fails.
How to Calculate Dielectric Strength?
The following steps outline how to calculate the Dielectric Strength.
- First, determine the breakdown voltage (BV) in kilovolts (kV).
- Next, determine the material thickness (T) in millimeters (mm).
- Use the formula from above = DS = BV / T.
- Finally, calculate the Dielectric Strength (DS) in kV/mm.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Breakdown Voltage (BV) = 30 kV
Material Thickness (T) = 2 mm
