Pienjännitteellä

Pienjännitteellä, a Finnish term, translates to "low voltage" in English. It refers to electrical systems and equipment operating at a voltage that is considered safe for human contact, generally below 1000 volts AC or 1500 volts DC. This voltage range is significantly lower than high voltage systems, which are used for power transmission and can be dangerous.

Low voltage applications are widespread in everyday life. They are commonly found in residential and commercial buildings for lighting, appliances, and electronic devices. Electronic circuits, such as those found in computers, mobile phones, and other gadgets, typically operate at very low voltages, often referred to as extra-low voltage. In industrial settings, low voltage is used for powering machinery and control systems where high voltage is not necessary or poses safety risks.

The primary advantage of low voltage systems is their inherent safety. Accidental contact with low voltage is far less likely to cause severe injury or electrocution compared to higher voltage levels. This makes it the preferred choice for applications where human interaction is frequent. However, it is important to note that even low voltage can cause a shock, and proper electrical safety practices should always be followed. The specific voltage limits for what is considered "low voltage" can vary slightly depending on regional regulations and standards.
