Substations Equipments Manufacturing at Navana Electronics Ltd.

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.
