DANSK DSF/IEC TS 62749 ED2 PDF

This Technical Specification specifies the expected characteristics of electricity at the supply terminals of public low, medium and high voltage, 50 Hz or 60 Hz, networks, as well as power quality assessment methods. NOTE 1 – The boundaries between the various voltage levels may be different for different countries/regions. In the context of this TS, the following terms for system voltage are used: • low voltage (LV) refers to UN ≤ 1 kV; • medium voltage (MV) refers to 1 kV < UN ≤ 35 kV; • high voltage (HV) refers to 35 kV < UN ≤ 230 kV; NOTE 2 – Because of existing network structures, in some countries/regions, the boundary between medium and high voltage can be different.
