Overvoltage protection of medium voltage power networks
The main technical problems associated with the formation and effects of overvoltages for equipment operated at MV power networks are discussed. The specific protection of that equipment against overvoltages and surge protection rules using metal oxide surge protection devices are presented. The paper identifies the appropriate ways of installing protective devices. It is stated that the individual protective systems are needed.
