when a three phase motor in running condition consumes 2A
in each phase,and if one of the phase gets fails what will
be the consumption in other two phases
Answers were Sorted based on User's Feedback
Answer / j.kesavan
when one phase fail ,other two phase take more current,coil
will burn out.

Answer / prashant
for a three phase motor do work properly all the 3 phases
must be active. In case if one of the phases fails then the
motor will not work properly ( SHOULD ACTUALLY STOP
ABRUPTLY )and may probably give a loud whining noice.

Answer / pratheesh
If one of the phase fails when a 3phase induction motor
is running, motor will continue running with a 25
percentage of more current in other 2phases.
If the thermal overload protection is not working
perfectly, the motor winding may burn.

Answer / gunasekaran
another two phase draw almost 2times current so winding may
getting heated up negative sequence relay will operate

Sir,In our company there are 3 caterpillar make(capacity:(1) 3.3KV,2.5MW(2)3.3KV,2.5MW & (3)3.3KV,1.9MW) & 1 deutz make (capacity:11KV,3.8MW)gas engines utilised,all are running in paralell. There are three transformer utilised,(1) 6.25MVA,3.3KV/22KV,Impedence voltage:6.7% used for two generator,both are 2.5MW(2)5.5MVA,3.3KV/22KV,Impedence voltage:7.2% used for one generator of 2.5MW & (3) 5.5MVA,11KV/22KV,Impedence voltage:7.8% used for one generator of 2.5MW.all generator breakers capacity of 1250Amps. Sir,I want the details of fault level calculation of generator,transformer individually & for whole system. If you require any information from me.feel free for contact me sir.pl.send the answer of my question as the earliest as possible.
