Answer / abdulgafar

A full load current of 250KVA DG Set is approximatly 350A.
Most of the DG Sets are designed to catter approximatly 10%
over load For a period of one hour hence a 250KVA dg set
can catter 385A For a period of one hour. you have applied
more load then the DG Set can catter/ deliver hence your DG
Set is triping automatically after about 3 min. hope i have
answered your question.

Answer / ajay

that is 250kva d.g.it will be give only 250-300amps
load...you will also give to 300a load and then check it

OR

hydrollic magnatising is very low,d.g.will run there
after voltage is not buildup,then d.g.is shuting down...

please do one thing short your battery
terminals and then give to connection it will be started.
