Lisäjännitteet

Lisäjännitteet, meaning "additional voltages" or "extra stresses" in Finnish, is a term used in certain engineering and technical contexts to describe extraneous or unintended electrical potential differences that can arise within a system. These are distinct from the primary operating voltages intended for the normal functioning of a device or circuit. Lisäjännitteet can manifest in various ways, such as leakage currents creating unintended voltage drops across components, capacitive coupling inducing voltages in adjacent conductors, or even static discharge events.

The presence of lisäjännitteet can have several detrimental effects. They can lead to inaccurate measurements by affecting sensor readings, cause unwanted activation or deactivation of components, or even contribute to the degradation of insulation over time, potentially leading to equipment failure or safety hazards. Identifying and mitigating lisäjännitteet is crucial for ensuring the reliable and safe operation of electronic and electrical systems. Techniques for managing these unwanted voltages often involve proper grounding, shielding, careful component selection, and design considerations that minimize susceptibility to external electromagnetic interference or internal parasitic effects.
