CONCLUSION :-
The Training of KUKAS,jaipur substation has been useful. We enjoyed the visit and we found out many things new while our visit and the work done there. In the end we learned about the Ideal and practical variation in working of the equipments. This visit was great-full for our knowledge.
The power sector of the country has been set on a path of vigorous and sustainable growth with self-reliance in all technological aspect. The country has aim at energy self-sufficiency. The growth in power sector helped millions of people in the country to secure employment. It is anticipated that a large part of the nation's wealth would be in power sector.
A necessary and important aspect of engineering course is practical training. It gives an engineer to face and tackle actual problems in the industries and field. The institute where the student studies can't provide him that practical knowledge on all always of learning. Until and unless the student has been exposed to its practical aspects, the study of the subject is incomplete. The artificial studies built the engineer in him by providing him pools of knowledge where as the practical application makes him agile and complete. If theoretical knowledge teaches the principal and policies, the practical exposure tells how to use those policies and principal in practical atmosphere. During training session the student learn to work in human laboratory.
I visit a 220kv G.S.S. R.R.V.P.L. kukas, Jaipur. I learnt there a lot. I came to know about CT and PT, distribution system, various transformers, relays, circuit breakers, conductors, LA etc. etc.
