Introduction

With the development of modern power system to the direction of extra-high voltage, large capacity, far distance transmission and application of advanced technologies the demand on the safety, stability and economic operation of power system became higher. A good grounding system is the fundamental insurance to keep the safe operation of the power system. The good grounding system should ensure the following:

To provide safety to personnel during normal and fault conditions by limiting step and touch potential.
To assur ....etc
