what happens to a turbo alternator if it get trip and 1 out
of 3 poles of circuit breaker in close condition
Answer Posted / a.p.nanjappa
Unbalanced current will develope till the upstream end
circuit breaker protection detect ( inverse time overcurent
and earth fault)and trips and isolate the fault.
The turbo alternator can run till negative sequence
charactristic constant limitation.I2t=K. Only generator
winding overheat and some time sparks,de[pends on fault.
It is also observed that major accident took place not only
damaging generator circcuit breaker pole damages,arcs and
body cabinet,arc chute burned,turbo alternater bearing
failure nted.
