Abstract
Growing demand for the availability of reliable and quality power has made the
job of substations more important. This can be achieved by establishing the new
substations, with most efficient and reliable equipments and taking at most care in their
operation and maintenance. These aspects make the Power & Energy System Engineers
to know more about the establishment, operation and maintenance of substations. In this
view training was undertaken at KPTCL, Bagalkot zone, Bagalkot.
During training an effort was made to know about 1) Factors considered for
establishing new substations 2) Importance of substation earthing 3) Study of
operations and maintenance of major substation equipments and 4) Responsibilities of
Electrical Engineer’s in establishing operation and maintenance of substations. Industrial
Training was obtained at the following substations of KPTCL.
1. 110/11 KV Sub-Station Shiraguppi Tq: Bilagi
2. 110/11 KV Sub-Station, Sadapur Tq: Mudhol
3. 110/11 KV Sub-Station, Neerabudhihal, Tq: Badami
4. 220/110/33/11 KV Sub-Station, Bagakot
5. 110/11 KV Sub-Station, Bagalkot
6. 220/110/11 KV Sub-Station, Bijapur (Near Shivagiri)
Establishing the Substations near load centers, installing the standard and efficient
equipment and by the well planned maintenances schedule, make the utilities to minimize
losses reduce the cost of operation and maintenance and enable them to supply quality
and reliable power to the consumers.
