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

Artificial Intelligence Substation Control

Controlling a substation by a fuzzy controller speeds up response time diminishes up the possibility of risks normally related to human operations. The automation of electric substation is an area under constant development Our research has focused on, the Selection of the magnitude to be controlled, Definition and implementation of the soft techniques, Elaboration of a programming tool to execute the control operations. it is possible to control the desir ....etc

The low or high resistivity soil layer formed in raining or freezing season affects the safety of grounding system, and leads the changes of grounding resistance of the grounding system, step and touch voltages on the ground surface.

This paper systematically discusses the seasonal influence on the safety of grounding system and the different methods to be adopted inorder to nullify the effect of seasonal changes.
Inorder to nullify the effect of the seasonal changes we can use long vertical grounding electrodes or by using chemically cha ....etc
