In operating power substation the roll of grounding is closely related with power system protection system.
The grounding system is very important in order to raise the power system reliability.
This paper presents a effect investigation for asymmetry properties, equivalent modeling of substations grounding system, overvoltage analysis by EMTP and operating examples of protection relay.
