Voltage classification in IEC 60038

Extra Low Voltage (ELV): This voltage range typically refers to voltages below 50 V AC or 120 V DC. ELV is commonly used for safety extra-low voltage (SELV) and protection extra-low voltage (PELV) applications. Low Voltage (LV): LV typically refers to voltages between 50 V and 1000 V AC or between 120 V and 1500 V DC. This range encompasses most standard household and industrial electrical systems. Medium Voltage (MV): MV refers to voltages between 1 kV (1000 V) and 35 kV (35,000 V) AC. Medium voltage is commonly used for distribution networks in industrial and commercial settings. High Voltage (HV): HV typically refers to voltages between 35 kV and 230 kV AC. High voltage is used for long-distance transmission of electrical power. Extra High Voltage (EHV): EHV refers to voltages between 230 kV and 1000 kV AC. Extra high voltage is used for long-distance transmission and bulk power transfer in regional and national electrical grids. Ultra High Voltage (UHV): UHV refers to voltages above 1000 kV AC. Ultra high voltage is used for very long-distance transmission and interconnecting large power systems. Source : IEC 60038 , Chat GPT
