During a temperature rise test of a bus duct, it is fed with 415 volts at 2000 amperes. Why dont we get an electric shock if we touch the bus bars?
7 12535what is the CT of protection and CT of metering ? what is class 5P10 & 5P20 and class PS ?
16 125103it is in our knowledge tht right plug of supply of residential suppy system is phase n other is neutral...howevr the battery charger of mobile works in both ways...i mean it is not restricted in only one direction.ny of the holder of charger can hav phase .so y is it not lik tht phase of supply must b connected 2 phase of charger...?
TATA,

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?

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
