Abstract
EN The contact resistance of the current path in a mechanical connector increases with rising current frequency due to the skin effect, which causes the current to concentrate near the surface of the conductor. This phenomenon is particularly significant in circuits with distorted current waveforms, often found in systems with non-linear loads. The increase in resistance leads to higher power losses within the contact system and the entire current path, contributing to excessive heating. As a result, the operational reliability and lifespan of the connector can be significantly reduced. To address this issue, this study determines a correction factor that allows for proper adjustment of the rated current in the mechanical connectors used in such conditions, ensuring improved performance and durability in practical applications.
