an infinite bus bar may be treated like a m/c with large
amount of inertia, so that the frequency will not change.
and the voltage and frequency remains unchanged regardless
of the equipment connected to it.
Infinite bus bar is the source where n numbers of
generators are loaded thereby impedance of the system
becomes so high that connecting or disconnecting any load
does not impact on voltage,frequency of the system.
The Voltage , Frequency of Infinite Busbars always remains
constant. This is what is called as Grid also
It is a three inch fan and i want it to rotate to other
direction .I've tried cutting the wire and reconnecting them
inverse like black to white and white to black ,but it won't
start rotating when i plug it in that way.And then it works
again when i rejoin the wire to the way it is. I don't know
what causing the problem.Is there anyone familiar with these
small mortor?Any suggestion would be appreciated.Thanks!!
Will it be OK to connect a 5MVA 33/6.6kV Ynd11 Transformer
to a Star connected Motor. Or on other words connecting a
Delta to a Star.
I have another 30MVA 33/11 Dyn11 and would it be practical
to convert it to Dd0 consequently converting the Voltage
Ratio to 33/6.35kV Dd0.
what is vector surge & vector shift? we have 25.3 MW(11kv)
generator & 11kv/132kv transformer, connected with with 132
kv grid.vector surge relay is tripping frequentaly.what is
permissible maximum limit for this.
