how we do Vector group ,magnetic balance and tap changer test in Transformer?
for 5KW resistive load can anyone please suggest me whether to go for UPS/Inverter or Generator depending upon cost calulations
I am designing new project sub station with 220 kV / 11 kV, 40 MVA capacity. This project have many recifier sets, which can generate 3rd harmonics. Now I have to select vector group of This transformer. To minimise 3rd harmonics, what care should I take in selection of Transformer Vecrtor group? If it is Y-Y with open Delta tertiary then what should be the rating & voltage of Tertiary Winding?
although ckt breakers have taken the place of old fuse. But instead of it , these older ones are still used in the industries and homes ? why .... what are their advantages and disadvantages ? which one is leading and winning the race and competition ?
what are the differences between 'exhaust fan', 'heavy-duty exhaust fan' & 'super heavy duty exhaust fan'. what are their power ratings ?
