Matalajännitev

Matalajännitev, meaning low voltage in Finnish, refers to electrical systems operating at a reduced voltage level. This is typically defined as alternating current (AC) voltages between 50 volts and 1000 volts, and direct current (DC) voltages between 120 volts and 1500 volts. These voltage ranges are considered safer for human contact compared to high-voltage systems, though still capable of causing harm under certain conditions.

Low-voltage systems are widely used in residential, commercial, and industrial settings. Common examples include standard household electrical outlets, lighting circuits, and power distribution within buildings. They are also employed in various electronic devices, telecommunications equipment, and electric vehicle charging infrastructure. The use of low voltage offers advantages in terms of safety, reduced insulation requirements, and often lower installation costs for the wiring itself.

However, even low voltage can present electrical hazards. The risk of electric shock depends on factors such as voltage level, current, resistance of the body, and the path the current takes through the body. Proper installation, maintenance, and adherence to electrical safety standards are crucial to mitigate these risks. Specialized training and certification are required for individuals working with electrical installations, including those involving low voltage. The classification of voltage levels can vary slightly between different regulatory bodies and countries.
