Relative permittivity in vacuum

WebTransformer oil relative permittivity is more than 1. It is only equal to 1 in vacuum. Therefore, relative permittivity indicates the ability of the dielectric to polarize and acquire electrical capacity. It is a nondimensional physical value. Relative permittivity of various materials differs. As was mentioned above, it is equal to 1 in vacuum. WebApr 13, 2024 · The latter is described by a relative permittivity ε g l = 4.82 and loss tangent tan δ = 5.4 × 10 − 3. The overall thickness along the z-direction of the “cylindrical” element, glass included, is z pl = 15 mm to emulate the uniform plasma slab and consistently with the geometry of the realized plasma discharge.
