It is a Maharatna company having 4 units each of 500 MW delivers 1850 MW to AP Grid and 150 MW to the Central Govt. Unit 4 is under overhauling, where i had an brief idea of excitation process, cooling system in generator, how is the steam inlet process to turbine, process from coal handling plant to boiler furnace, why turbine driven boiler feed water pumps are used and baaring process i. e. initial starting of unit. I have learned how the new cable is tested and how the entire process is going on. Management provides all the required facilities for the process of learning. Myself and my batch mates will share the knowledge of what we learned that day. The hardest part is identifying the fault where an individual knowledge gets improved. The most enjoyable part is learning the things which i don`t know.
