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.

- two pumps must work with them at the same time but if the first pump start the second pump  must delayed for some time to start  also , with motor rated power = 90 KW and rated voltage = 380 V and rated power factor = 0.85 lag please draw the power and control circuit for it and determine all circuit components parameters that you use it
