pienjännitteisillä

Pienjännitteisillä, a Finnish term, translates to "low-voltage" in English. It refers to electrical systems and equipment that operate at a reduced voltage level compared to high-voltage systems. Typically, low-voltage installations are found in residential, commercial, and industrial settings for general power distribution.

The exact voltage range considered "low voltage" can vary slightly by region and standard. However, it generally encompasses voltages up to 1000 volts AC (alternating current) or 1500 volts DC (direct current). This is in contrast to medium-voltage and high-voltage systems, which are used for power transmission over longer distances and at higher capacities.

Safety is a primary consideration with low-voltage systems. While less dangerous than high-voltage systems, improper handling or faulty equipment can still pose risks of electric shock or fire. Therefore, electrical codes and regulations are in place to ensure the safe design, installation, and maintenance of these systems. Common examples of low-voltage applications include household appliances, lighting circuits, electronic devices, and power outlets. The widespread use of low-voltage technology makes it fundamental to modern electrical infrastructure.
