Abstract The main goals of bonding and grounding are to ensure the safety for users
and the normal operation for equipments, to protect the equipments and power
distribution system, to reduce the noise of equipments, and to improve the reliability of
equipments. This thesis mainly includes four parts, the first part is the definitions of
common bonding network and isolated bonding network,the second part is the
requirements for bonding and grounding of telecommunication equipment in GR-CORE-
1089 standard, the third part is the requirements of grounding systems for network
equipments or AC and DC distribution, and the last part is the requirements for the
equipment grounding conductors.
