| Is This Answer Correct ? | 11 Yes | 6 No |
1.polarity must be same ( Must be full fill )
2.phase sequence must be same (Must be full fill )
3.turns transformation ratio must be sane ( Desired )
4.frequency must be same ( Must be full Fill )
5.% Impedence must be same ( Desired as to ensure equall
load sharing of both the transformer

Answer / vilas
1)Transformer primery voltage rating should be same.
2)phase sequence should be same .
3)polarity should be same.
4) Vector group should be same ,for example :dy11 etc.
These point to be considered while making parallel
operation of the tansformer.

what are the principles of a booster converter?
what is on line transformer and off line transformer.
WHY TRANSFORMER IS MEASURED IN KVA?
We have a 33/11kv switchyard having 12.5 MVA power transformer. We export & import power through this transformer. When we export power, the PF will be depend on GRID PF & when we import power the PF will be depend on our load PF. but the problem is that,when neither we export nor import but our 33KV vCB is in close position,our meter read the power factor 0.14 to 0.25 at that moment. So how can be we improve the power factor at that moment.
How can we calculate the resistance of earthing & how can we control it?
