high voltage means the set of nominal voltage levels that are used in power systems for bulk transmission of electricity in the range of 44kV<Un 220 kV. [ SANS 1019];
High voltage bus means the electrical circuit, including the coupling system for charging the REESS that operates on high voltage.
low voltage means the set of nominal voltage levels that are used for the distribution of electricity and whose upper limit is generally accepted to be an a.c. voltage of 1000V ( or a d.c. voltage of 1500 V). [SANS 1019]
X-ray high-voltage generator means a device which transforms electrical energy from the potential supplied by the x-ray control to the tube operating potential. The device may also include means for transforming alternating current to direct current, filament transformers for the x-ray tube(s), high-voltage switches, electrical protective devices, and other appropriate elements.
voltage means the root-mean-square value of electrical potential between two conductors.
