A three phase load, around 4 km away from the 11/0.433KV
distribution transformer (Neutral of Transformer is
solidily earthed) and consisting of mainly very costly and
sensitive electronic equipments is giving trouble due to
high voltage difference between neutral and body earth.
Whether this problem can addressed by connecting neutral at
the load point solidly to earth?
Answer Posted / 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.

We have a distribution transformer of 750KVA/11kv/440v and an AVR (Servo Stabilizer) of 750KVA on the LT side of distribution transformer. Also we have an ACB of 1200A on the output of distribution transformer (that is on the input of AVR). We want to have an MCCB on the output of AVR. What should be the rating?
