The Novocontrol Alpha Dielectric Analyzer is a state-of-the-art system for the investigation of the dielectric and electrical properties of materials over a broad frequency and temperature range. The technique measures the dielectric permittivity, dielectric losses, conductivity, and polarization processes, providing valuable insights into molecular dynamics, charge transport, and interfacial phenomena.
The instrument is particularly suited for the characterization of polymeric insulation systems used in electrical and electronic applications, enabling the assessment of material performance, aging, degradation, and reliability under operating conditions. Broadband dielectric spectroscopy is widely employed in the development of insulating polymers, nanocomposites, cable insulation materials, and dielectric coatings.

Thermally Stimulated Depolarization Currents (TSDC) is a highly sensitive dielectric characterization technique used to investigate charge trapping, molecular relaxations, and polarization phenomena in insulating materials. During the measurement, a sample is electrically polarized under a controlled electric field, cooled to freeze the polarization state, and subsequently heated while monitoring the depolarization current released as trapped charges and dipoles relax.
TSDC is particularly valuable for the study of polymeric insulation systems, providing detailed information on charge storage mechanisms, trap energy distributions, space charge behavior, and aging effects. The technique is widely applied in the development and evaluation of advanced insulating materials for power cables, capacitors, electrical machines, and electronic components.
