jännitekestosta

Jännitekesto refers to the maximum voltage that an electrical insulation material or component can withstand without breaking down. It is a critical parameter in electrical engineering, dictating the safe operating limits of various devices and systems. Jännitekesto is influenced by several factors, including the type of insulating material, its thickness, the presence of any contaminants, temperature, and the duration of the applied voltage.

Different types of insulation materials possess varying jännitekesto ratings. For example, ceramics and glass generally have very high jännitekesto, making them suitable for high-voltage applications. Polymers, while offering flexibility and ease of processing, have a range of jännitekesto values depending on their specific composition.

Understanding jännitekesto is essential for designing reliable and safe electrical equipment. Exceeding the jännitekesto can lead to insulation failure, resulting in short circuits, equipment damage, and potential fire hazards. Therefore, engineers carefully select insulation materials and design components to ensure that the applied voltages remain well within the material's jännitekesto limits. Testing is often performed to verify the jännitekesto of insulation under various conditions.
