:) respected sir I have one generator having 250kva capacity.I want to connect the existing load with this generator ,existing load is 140kw.and also tell me how I have share the load equally

This is homework, and should be handled of in the homework department.

But I'll give you some hints to answer your own question :

"i have one generator having 250kva capacity.i want to connect the existing load with this generator ,existing load is 140kw.and also tell me how i have share the load equally"

A 250 KVA generator provides that power over 3 phases.
Your load has to be powered from these 3 phases.

The only way to share the load equally is over the 3 phases of the generator.

So what is your load?
How is this load currently spread over 3 phases?
And how would you spread the load if it has to be shared equally?

Success !

Yep, you read into the problem. 3 phase is a good assumption. Homework is too. As another answer, the 140 kW load should have already been distributed equally among the phases, so no adjustment is necessary.

PS: "W" as in Watts should be capitalized because it's a proper name. "A", for Ampere should also for the same reason.

So should be "V" (not "v") in kVA

Define the load sharing of generator

Eample: You can share the Air conditioning load with cooking, but you may not be able to share a "sump pump" load. You may be able to share multiple refrigerator/freezer loads, at least manually.
