hi frienda We have 750kva cater pillet dg set we are fasing
one diffrent proublam in dg we are start dg set after one
mint applying load around 450a load but dg was run 3 Or 4
mints after 3 mints dg was shuding down automatic how to
face this proublam pls tel any budy
I have a relay contact rated at 220v dc which is supplied
with a 24vdc from the panel,for it to trip the
dampers(24vdc).What if the application of the relay changes
so that it should work at its rated 220vdc then will it work
at 24vdc supply given or any other consideration needs to be

I have a drawing of a wound rotor induction motor for a
crane. This crane motor has 5 forward speeds & 5 reverse
speed implemented of course with different amount of
resistance for each speed setting selected. What has got me
scratching around is the fact that 8 of the 10 speed
selections switch in uneven (unbalanced) amounts of
resistances on each of the 3 connections to the motor's
rotor.Can this be possible? I would have assumed this would
produce unbalanced rotor currents and therefore vibration
in the motor. I would greatly appreciate anyone's comments
