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.
why capacitance effect is predominant in underground cable
transmission and inductance effect is predominant in over
head line transmission?
upto how much low RPM we will run the commercial motor
which is run through VFD without any problem occurs in
motor.Motor rating Duty is S1 & RPM is 1400.
We have got the HT connection of 1000 KVA in which we have
installed a seprate APFC panel at the PCC end & seprate KWH
meter is installed. My question is that does the KWH
reading shown in the meter is a part of the Consumption ????

Can any one know what are the symbols at the down (below)
the analog ammeter??? there are 4 symbols which are
from where the self excitrd induction generator get the
power?why is the voltage regulation is poor of seig?
