MESSAGE I am glad to know that Operation department has prepared Stage-III Turbine schematics in the form of booklet titled “LINE TRACE”. Successful organizations understand that learning leads to business leverage. This book is designed user friendly containing all the intricate details of schemes for easy learning, efficient monitoring, safe isolation and normalization of systems. The book is found to be very convenient for day to day jobs and users can easily understand and visualize the systems and schemes. The schemes drawn in this booklet titled LINE TRACE contain fine details of the schemes as erected in Unit-7 Turbine side. I am sure that all employees and new entrants to Operation will make use of this book as an immediate reference for improving their skills. I convey my warmest greetings to all employees in Operation department and wish them all success.

FOREWORD

Date:22-12-2005

Efficient and reliable operation of Thermal Power Station mainly depends upon the awareness of various systems and schemes by operation & Maintenance personal about the plant. Operation department attaches great importance for training and development interventions of all its employees technically by providing all the necessary material such as schematics. The compiler has immensely involved and drawn the schemes to lend a new edge for achieving better operation practices. The book will be useful in improving knowledge and skills of the operation fraternity. I am confident that all the employees of Stage-III operation will make use of this schematic booklet for immediate reference and enhancing their skills, thereby improving productivity. I hope this book will be of great help to one and all in operation & Maintenance departments.
