minimijännitteet

Minimijännitteet, also known as extra-low voltage (ELV) in English, refers to a range of electrical voltages that are considered safe for humans to touch. The exact definition and limits for minimijännitteet vary by region and specific application, but they generally fall below standard mains voltage levels. These voltages are typically achieved through transformers, batteries, or other power supplies that reduce higher voltages to safer levels.

The primary purpose of employing minimijännitteet is to enhance electrical safety. In environments where there is a risk of contact with electrical circuits, such as in homes, schools, or public spaces, using ELV significantly reduces the likelihood of electric shock. This is crucial for protecting individuals, especially children, from potential harm. Common applications include low-voltage lighting systems, electronic devices, toys, and certain types of industrial equipment.

The concept of minimijännitteet is a fundamental principle in electrical engineering and safety regulations. Standards bodies define specific voltage thresholds for different categories of ELV, often differentiating between voltages that are safe under dry conditions versus those that are safe even in damp or wet environments. Adherence to these standards ensures that electrical installations and devices are designed and operated with the utmost consideration for human safety.
