Lågspänningskretsar

Lågspänningskretsar, often referred to as LV circuits, are electrical circuits that operate at reduced voltage levels. This is typically defined as voltages below 1000 volts alternating current (AC) or 1500 volts direct current (DC). The primary advantage of using low voltage is enhanced safety, as the risk of electric shock is significantly reduced compared to high-voltage systems. These circuits are prevalent in a wide array of applications.

In residential and commercial buildings, low-voltage circuits are used for general lighting, power outlets, and the distribution of electricity for most appliances. They are also fundamental to electronic devices such as computers, smartphones, and televisions, where sensitive components require carefully controlled and safe voltage levels. Telecommunication systems, including telephone lines and network cabling, also operate on low voltage to ensure reliable data transmission and user safety.

The design and installation of lågspänningskretsar must still adhere to strict safety standards and regulations to prevent electrical hazards and ensure proper functionality. Protection devices like circuit breakers and fuses are essential components of low-voltage systems, designed to interrupt the flow of current in case of overloads or short circuits, thereby safeguarding both equipment and people.
