Research of electrical safety conditions in mains with voltage up to 1000 v with deafly grounded neutral

AbstractThe paper presents the results of a theoretical study of safety conditions for various groups of electrical equipment that affect single-phase networks in order to prevent short circuits on the case. The authors analyzed the “PUE” requirement for grounding systems and, as a result, revealed that the “PUE” requirements for grounding systems do not provide sufficient safety and supplements are needed to more clearly regulate the procedure for re-grounding the neutral wire.
