explain in detail HV & LV bushing connection in power
transformer (110 / 11 kv 16 MVA)
Answer Posted / talluri
Bushing connections at HV side is 3 and LV side is 4 with
highly insulated.Normally at substations 110/33 transformer
will be used and then same 33kv will be step down to 11kv
to avoid losses.

Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
why it is not advisable to run low rating (19KVA) DG sets in parallel for long durations even though they are provided with droop ckts (QDC)
