Leckstromdichte

Leckstromdichte refers to the electric current that flows through an insulating material or a gap under a specific voltage. It is a measure of the imperfection of an insulator, indicating how much current "leaks" through it rather than being perfectly blocked. The term "density" implies that this current is considered per unit area, typically expressed in amperes per square meter (A/m²).

High leckstromdichte suggests poor insulating properties, which can lead to energy loss, component malfunction, and in extreme cases, safety hazards. Factors influencing leckstromdichte include the material's resistivity, thickness, temperature, humidity, and the applied electric field strength. For example, as temperature increases, the resistivity of most insulators decreases, leading to a higher leckstromdichte. Similarly, moisture on or within an insulator can significantly increase leckstromdichte by providing a more conductive path.

In electrical engineering, minimizing leckstromdichte is crucial for designing reliable and efficient systems. This is achieved by selecting appropriate insulating materials with high resistivity, ensuring proper insulation thickness, and maintaining clean and dry operating environments. Leckstromdichte is a key parameter in the characterization and testing of insulating materials and components used in high-voltage applications, electronic devices, and power systems. It is often measured under specific standardized conditions to allow for consistent comparison.
