Dielectric characteristics
This test method is used to calculate dielectric characteristics.
| Test specimen | Ø 80 mm, 2 mm thick |
| Test voltage | 0,1 V to 2,00 V (frequency-dependent) |
| Test frequency | Ø 80 mm, 2 mm thick |
| Capacitance | Ø 80 mm, 2 mm thick |
| Loss factor | 0,0001 to 1,0 (frequency-dependent) |
| Temperature range | -40°C to 200°C |
Results of the test method
- The dielectric constant εr is an unknown proportional number. It indicates the number of times the capacitance of a given capacitor is multiplied if an insulating material is introduced into it instead of vacuum.
- The loss factor tan δ is the tangent of the complementary angle to the phase angle φ at 90°. It represents a measure of the energy absorbed by the insulating material in the alternating field.
