In electrical system fuse acts as protection device and
depending on application different type of fuse is to
select. Out of these different type of fuses HRC is also
one of the type and it stands for " High Rupting Capacity".
This type of fuses normally used where some delay is
acceptable for protecting the system.
a solar energy installation utilizes a three phase bridge
converter to feed energy into power system through a
transformer of 400v/400v.the energy is collected in a bank
of 400v battery and is connected to converter through a
large filter choke of resistance 10ohms.1.the maximum
current through the battrey will be.2.the kva rating of the
input transformer is.
Can u explain : how capacitor act when the supply is given
is a.c and d.c.
I know that when d.c supply is given then the capacitor
charges and becomes open circuited.
But please say about when a.c is given.
I have seen that when a.c supply is given ,it charges and
But when we plug in capacitor to our daily supply and take
it out ,then we join those wires spark will appear,which
seems charge is present ,but when a.c is given it should
charge and discharge
some practicle study shows that the reactive power at the
receiving end is not equal to the reactive power at the
sending end.But according to theory the reactive power is
exchanged by different parts of the network – capacitors
and reactors permanently, but is never consumed or produced.
Then Where that reacrtive power loss occuring?is there any
formula to calculate reactive power loss?
