Insulation of rods (coils) of machines with power of more than 5 MW and voltage greater than 6 kV for the control of manufacturing technology is subjected to an additional test : measurement of the dielectric loss tangent
tg[delta] of insulation, depending on the applied test voltage at normal air temperature.
EM loss capacity can be described by dielectric loss tangent
It also increases the storage modulus, decreases the loss modulus and loss tangent
The geometry of the initial design is imported from a SAT file; then electrical properties of the materials, such as permittivity and dielectric loss tangent
, permeability and magnetic loss tangent
, bulk electrical conductivity, and magnetic saturation are defined.
A process described in  is used to find the relative permittivity and loss tangent
of various paints.
d]), dielectric constant ([epsilon]'),dielectric loss ([epsilon]"), loss tangent
(tan[delta]) and molar polarization ([P.
The depth of penetration d of microwaves into a dielectric is a function of the total dielectric loss tangent
and the vacuum wavelength [[lambda].
Since the materials[right arrow] are considered to be nonmetallic, thus a measure of the energy lost in the form of heat is called the loss tangent
A controlled stress rheometer was used to obtain small-amplitude oscillatory shear flow measurements of the storage modulus, the loss modulus, and the loss tangent
tan delta using vane geometry.
Moisture also affects the electrical properties of a dielectric by altering its dielectric constant and loss tangent
Using proprietary substrates that feature dielectric constants between 4 and 152, and a dielectric loss tangent
as low as 0.
The product's low dielectric constant and loss tangent
are stable throughout a broad range of frequencies from 1 MHz to 40 GHz and temperatures from -55[degrees]C to +200[degrees]C.
