Description: of the electrical power system. At the time of transformer energization high current is drawn by the transformer known as the inrush current. This current is nearly ten times more than the full load current of transformer. It produces mechanical stress on transformer and also affects the windings and bushings of the transformer. The large switching transient current affects malfunction of protection system of power system and the different equipments connected to system. So the inrush current should be minimized. There are different methods used to minimize the inrush current such as volt second balance, series compensator, point on wave switching method etc. This paper focuses on point on wave switching method. It also explains the results for inrush current of three phase transformer with and without point on wave switching method. A test is driven on 450 kVA, 500kV/230kV grounded Y/D transformer in MATLAB/SIMLINK environment. It also focuses on Platform: |

Description: Transformer is one of the costliest apparatus in an
electrical power supply network which play vital role in an
electrical power system. It is expected that all transformers
installed in a substation must function optimally under normal
as well transient conditions. Their satisfactory performance of
transformers can be ensured by making use of latest trends in
condition based monitoring. This helps not only in providing
interruption free electricity supply but also help in enhancing
attain prolonged residual life and hence capital management of
the utilities. Forecasting transformer costs by its manufacturer
and industrial companies has always been an area of interest
especially in modern era of technology advancements when
newer and newer material are pouring into market for the use
by manufacturers. Platform: |
