If Two Generators are working parellel in a network and
suddenly the field of one Generator get weakened What will
happened if there is no reverse power relay fixed in that
Generator panel????
Answer Posted / raju pohane
if in running condition one generator field wdg became weak
that time this generator will go in field weakening
position and speed will suddenly high and generator will
trip on over speed due to tripping in one generator, load
will shift on another generator and if there will no span
for load in another generator it will also trip.

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
