A promising career in engineering beckoned me pretty early in life. I had just completed my school education. My credentials to write this technical book have more to do with the hands-on experience gained from over 50 years of working in some prestigious engineering companies than with the knowledge acquired from academic institutions.
After a brief stint in Government employment, I found it was not my cup of tea and so I joined an EHT transmission line engineering and construction company. Impressed by my performance, the company sent me as site in-charge wherever I was assigned. I learnt soon that I would end up just controlling labour, supervising payments and accounting the material, if I did not acquire sound technical knowledge of the work responsibilities.
On an occasion, we had completed construction of a 15 mw power house and were to finalise and submit material accounting to the AP State Electricity Board before we could hand over the site to them. The responsibility fell on me as the regular technical site in-charge was deputed elsewhere. I was barely 23 and hot-blooded. I used to be blunt to the point of being rude. So, I had few friends or well-wishers who could help me. I changed my ways, won them back and finalised the account.
My efforts to complete a diploma course through distance education did not succeed because of the hectic work schedule lasting up to 16 hours a day. I did not stop reading technical literature on the subject to upgrade and update my knowledge. I achieved the capacity to independently handle an EHT transmission line project on my own and thus earned a place in the management cadre of M/s EMC Steelal Ltd, Kolkatta. A comprehensive report on the training I underwent in this company was much appreciated. I had also successfully handled the assignment entrusted by Mr. Arora, general manager (foreign projects), to do a project report for laying 100-km , 220KV line passing through hilly region, paddy fields and patches of dry land.
I was immediately assigned to take up stringing of 360 km of 400 KV line from Bhilai to Kuradi. Barely two months later, I was sent post haste to Dubai, where the company ran into trouble on account of labour strike. I completed two projects there on time. Initially, the Dubai Electricity Company did not accept me as a field engineer as it had serious reservations about my technical competence. They accepted me as site engineer only after the DEC and the British consultants M/ Kennedy & Dankin, observed my performance for 3 months and were satisfied.
The EMC firm promoted me and asked me to do a project in Libya. I chose to quit and take up UHT line work on my own. Technical knowledge and skill in line survey and conductor stringing works are crucial to EHT transmission line construction works.
In later years, I focused on survey work as it formed the backbone of any UHT project. It is not easy to work abroad or with foreign consultants unless we measure up to their exacting expectations in technical skills. I had worked with the British, Finnish, German, Italian and American consultants in India and abroad. I had worked for the NTPC, the Power Grid Corporation, the State Electricity Boards and the MNCs in India.
I have striven hard to present in this book, material I gathered over the past half century in UHT lines field operations. I have also tried to update the subject matter and cover major trends and developments in the UHT transmission projects.
I sincerely hope that this book will be of immense value and utility to practising engineers in the field of UHT transmission projects.
