Pienjännitealueen
Pienjännitealueen is a Finnish term that translates to "low-voltage area." It refers to a specific geographical region or electrical installation where the primary voltage supplied is at a low level, typically defined by national regulations. In Finland, low voltage is generally considered to be alternating current (AC) voltages up to 1000 volts and direct current (DC) voltages up to 1500 volts. This designation is important for safety regulations and the types of electrical equipment that can be used within these areas. Examples of pienjännitealueen include most residential homes, commercial buildings, and many industrial facilities where the power requirements do not necessitate higher voltage distribution. The transition from medium or high voltage to low voltage occurs at substations or local transformers. Electrical work and installations within pienjännitealueen must adhere to specific safety standards to prevent electric shock and fire hazards. The design and operation of electrical systems in these areas are governed by Finnish electrical safety laws and standards, such as those set by Tukes (the Finnish Safety and Chemicals Agency).
