Answer / parul

Check the load circuit properly.Check the transformer at
open and short circuits.Isolate the neutral earthing in the
substation transformer and check the voltage in all phases
to find out whether transformer is the problem or your load.

After considering all above checks you may do the earthing
of neutral point in your load.

Answer / velusamy

check the overall earth pit resistance value and it
should be less than one ohms

Answer / wareagle

It is an absurdity to try to provide 433 volt electrical
service to a load that is 4 KM away. You need to install 11
kv line to the load and then install the transformer. You
won't have a problem. There is always a difference between
the earth and a neutral. If that is a problem, bond them
together. They should be anyway.

Is it required to lay GI wires along with GI/MS conduits from one point to another point though separate earthing cable is conncted from DB to Socket?

1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
