Analyses of the grid resistance measurements of an operating transformer station
(Budapest University of Technology and Economics, 2009)
This paper presents a non-conventionally installed HV/MV underground substation from the point of view grid resistance. The effects of the infeed high voltage (HV) cables and the connected medium voltage (MV) distribution ...
Circumstances affecting the protection against electrode potential rise (EPR)
(Budapest University of Technology and Economics, 2009)
In this paper the grid resistance of substations with different earth electrode and soil structures is investigated by simulation studies with the use of CDEGS (Current Distribution, Electromagnetic Fields, Grounding and ...
