Abstract:
To fulfill the requirements to be a B.Sc Engineer from East West University, we can choose any
one option from lndustrial Training or Project work. We have chosen lndustrial Training. We did
our training at NA V ANA Electronics Ltd. We did our major in power engineering. At NA V ANA we have gathered our practical knowledge about Distribution transformer, Breaker
and Switchgear items (LT, HT and PFn, IPS (Instant Power Supply), UPS (Uninterruptible
Power Supply), IVS (Industrial Voltage Stabilizer). We have seen the whole process of
manufacturing of the above equipments and also we have seen some testing procedure of the
equipments. Before doing this internship we had limited bookish knowledge about transformer,
Switchgear, IPS, UPS and IVS. But now we have knowledge about these equipments comparing
to before. In transformer section we have seen the whole process step by step. We learnt how to
test a transf<mner. We gathered knowledge about coil winding, CQfe assembly, CQfe-coil
assembly, tank up, transformer tank processing. We have also seen the manufacturing steps of
distribution transf<mner and Switchgear items. We have learnt Low Tension (L T) panel and High
Tension (HT) panel, what types of breaker are used for LT and HT panel. It has also been made
clear to us that why power factor is important and how we can improve power factor by using Power Factor Improvement (PFI) panel and why we use Circuit Breaker, types of Circuit
Breaker available. Also we have seen the paint and fabrication process of these items.
