Capacitors

dielectric loss

Electrical equipment; Capacitors

The time rate at which electric energy is transformed into heat in a dielectric when it is subjected to a changing electric field.

dielectric loss angle

Electrical equipment; Capacitors

The difference between ninety degress (90°) and the dielectric phase angle.

The angular difference in phase between the sinusoidal alternating potential difference applied to a dielectric and the component of the resulting alternating current having the same period as the ...

dielectric power factor

Electrical equipment; Capacitors

The cosine of the dielectric phase angle (or sine of the dielectric loss angle).

dielectric strength

Electrical equipment; Capacitors

The voltage which an insulating material can withstand before breakdown (puncture) occurs, usually expressed as a voltage gradient (such as volts per mil). The voltage figure used is the average RMS ...

dielectric test

Electrical equipment; Capacitors

Tests which consist of the application of a voltage higher than the rated voltage for a specified time to determine the adequacy against breakdown of insulating materials and spacings under normal ...
