<para> Field mill instruments are often employed for the measurement of electric fields, electric charges, voltage potentials, and atmospheric effects. This paper discusses in more detail the application of a field mill for measuring dc voltages in high-voltage laboratories. Some specific problems, which arise when voltages in the kilovolt or megavolt range have to be measured, are emphasized...
Field mill instruments are often employed for the measurement of electric fields, electric charges, voltage potentials and atmospheric effects. This paper discusses in more detail the application of a field mill for measuring DC voltages in high-voltage laboratories. Some specific problems, arising when voltages in the kV or MV range have to be measured, are emphasized. Safety, signal transmission...
Due to the increased unbalanced loading of electrical grids, the penetration of power electronics and an increased number of switching phenomena in low and medium voltage grids, it is obvious that electrical insulation systems are no longer subjected to only a 50 Hz, purely sinusoidal voltage. The existence of fast transients, switching impulses or in general combined voltages with at least two clearly...
