dielectric loss

Additional energy losses occur as a result of dielectric loss in the cable insulation.

Dielectric loss of air is extremely low for high frequency electric or magnetic fields.

However, losses such as proximity effect and dielectric losses are still present.

In practice, the dielectric losses of the cable system at 0.1 Hz with an off-line test.

At high frequencies, another effect called dielectric loss becomes significant, adding to the losses caused by resistance.

There are two main components to these losses, the metal loss and the dielectric loss.

In other processes, heat is produced within the workpiece by induction or dielectric losses.

The dielectric losses can likewise be ignored.

Polar molecules may dissipate high-frequency energy, causing parasitic dielectric losses.

Dielectric loss and non-zero DC conductivity in materials cause absorption.

The relaxation, a peak in mechanical or dielectric loss at a particular frequency, had previously been attributed to a type of molecular flexibility.

In addition, capacitance between turns causes dielectric losses in the insulation which coats the wires.

Its dielectric properties are poor due to high content of polar groups, the dielectric loss is moderately high.

However, at higher frequencies (such as visible light), dielectric loss may increase absorption significantly, reducing the material's transparency to these frequencies.

The largest share of these losses in larger capacitors is usually the frequency dependent ohmic dielectric losses.

The methods described included all the heat generation mechanisms from a power cable (conductor loss, dielectric loss and shield loss).

Once the complex permittivity of the material is known, we can easily calculate its effective conductivity and dielectric loss tangent as:

Interestingly, the dielectric loss appears to match the loss modulus more closely than the loss compliance when data are compared for the same system.

Dielectric heating involves the heating of electrically insulating materials by dielectric loss.

An electrical signal in a cable gets weaker the further it travels, due to energy dissipated in conductor resistance and dielectric losses.

Insulation is either absent, with spacers, or low permittivity, low loss materials such as silk to minimise dielectric losses.

Because dielectric losses increase with increasing frequency, the specified AC voltage has to be derated at higher frequencies.

As with the parallel-coupled line filter, the advantage of a mechanical arrangement that does not require insulators for support is that dielectric losses are eliminated.

For smaller components, especially for wet electrolytic capacitors, conductivity of liquid electrolytes may exceed dielectric losses.

Compared to other polymers the BCB has a low dielectric constant and dielectric loss.
