Low voltage
Roof stand with overhead lines, part of the low-voltage network
Alternating voltages up to 1000 volts and direct voltages up to 1500 volts are referred to as low voltage . The area of low voltage includes low voltage networks ( 230/400 volts ), but also extra-low voltages . Legal regulations for low-voltage systems within the EU are laid down in the Low-Voltage Directive.
| Voltage ranges | AC | DC | |
|---|---|---|---|
| High voltage | > 1000 V | > 1500 V | |
| Low voltage | ≤ 1000 V | ≤ 1500 V | |
| Low voltage | ≤ 50 V | ≤ 120 V | |
Higher electrical voltages are referred to as high voltage , which in the field of electrical power engineering is divided into medium voltage , high voltage and maximum voltage . The limit values are not clearly defined here.
