Seasonal Influence on Safety of Substation Grounding

Introduction
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 c ....etc

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

Although grinding is considered one of the more established manufacturing processes, it is still relatively poorly understood. In particular, the interaction of the wheel with the workpiece at times seems more like an art than a science. In this presentation, a 3-D topographic measurement approach which encompasses both the wheel and the workpiece will be presented. The topographic information obtained from the wheel will be applied to a model to predict the workpiece surface generated which will then be verified by experimentation. The prelimi ....etc
