high voltage network (HVN)
The term high voltage and the associated voltage values depend on the context in which they are used. In energy technology, the voltage values are many times higher than in household and measurement technology.
In general, high voltage refers to voltages with which a spark can be generated in the air or which cause an electric shock when touched.
High voltage can be voltages that exist between two current-carrying lines or between a line and ground. In power engineering, high voltages are voltages between 60 kV and 110 kV. Since the classification of voltages is not standardized, the specifications may vary. Such high voltages are used in power supply networks for overhead lines and for connection to power plants.
The high-voltage range still knows the range of extra-high voltages, which is above 220 kV. Below the high voltage range are the medium voltages, and below that the low voltages. Medium voltages are voltages between 3 kV and 30 kV, low voltages are below 1 kV.
