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

Diesel engines exhausting gaseous emission and particulate matter have long been regarded as one of the major air pollution sources, particularly in metropolitan areas, and have been a source of serious public concern for a long time. There has been numerous research in the field of reduction of these pollutants since diesel engines came to major use. Major emissions from a diesel engine are NOx, SOx, CO and particulate matter (PM).amongst these pollutants CO and SOx and some quantity of particulate matters are reduced by some after treatment m ....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

Abstract
The influence of the diesel particulate filter additives (DPA) SATACEN and EOLYS on biodiesel fuel quality has been evaluated. Both additives significantly affected the oxidation stability of neat biodiesel. The influence on acid values and CFPP was found to be only small. Combination of diesel additives with biodiesel additives like oxidation stability and CFPP improvers led to similar results. Results indicated that DPA also lowered the efficiency of the oxidation stability improver Baynox. Furthermore, the CFPP additives Chimec an ....etc

WHAT IS IT..????
It is a graphical plot between the different temperatures, Carbon content and phases of iron.
It is known as equilibrium diagram because the state of the system remains constant over a period of time
To produce the diagram or the graphical plot a series of cooling and heating curves of Iron with varying Carbon content was obtained.
Then the critical points of the cooling and heating curve were plotted on a temperature vs C content plot and thus the Iron carb ....etc
