Answer / m nanda kishore

the grid is also referred as infinite bus bar in terms of
synchronisation but it also implies fixed voltage,fixed
frequency,phase seuence,phase voltages

Answer / motilal sahu

INFINITE BUS BAR IS CONDUCTIVE WIRE IN WHICH INFINITE
ALTERNATOR IS CONNECTED TO MAINTAIN fixed voltage,fixed
frequency,phase seuence,phase voltages

Answer / pankaj

infinite bus bars means the whose parameters like voltage,
frquency, phase sequense remains constant even after change
in parameters in the local ckts.

Answer / deepak kumar

An infinite bus bar is a parallely connected network of
ALTERNATORS, whose frequency and voltage remains
constantregardless of power drawn or supplied from it.

Answer / sagar alias jacky

infinite bus bar has constant frequency and voltage......

Answer / pankaj kumar verma

Infinite busbar is a whose parameters like voltage,
frequency and phase sequence remain constanat even change
in the connected load to the infinite busbar.

Answer / satish

INFINITE BUS BAR is a very large conductive circuit in which
infinite Alternators are connected to maintain fixed
voltage,fixed frequency,phase sequence and phase voltages.

Answer / sujan kumar

an improvement to the above answers

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.

Answer / swarn

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

Answer / anil kumar verma

Infinite bus bar is the node in a power sustem where
many generators can be connected without affecting the
voltage & frequency of the system.
