in my plant 100% feedwater control v/v is air to close but
due to instrument air fail,the valve opens but instead of
drum level high its get tripped in low low drum level.the
urv of level tx is 0 and lrv is -800.pls tell me the reason.
for such behaviour.
in our 6.6kv motor feeder[it is having two sources from
Bus A&B] earth fault relay is acting, we checked CBCT
connection and cable meggerd values found very good still
earth fault acting during first two are three start after
that it will hold. please clarify what was the reason. if
same motor is starting from other Bus-A it will start.
For two systems transmitting the same amount of real power,
the system with the lower power factor will have higher
circulating currents due to energy that returns to the
source from energy storage in the load.???
what is meaning of 230volts ac 50hzs ac supply is it rms or
to getting ac 230v what amount of max voltage they will send
I am Darshan S D completed BE in Mechanical & also completed
my MBA in Finance & Marketing.Presently i am working in
