Answer Posted / rajesh babu.d
CRGO - Means "Cold rolled Grain oriented" Silicon steel.
The line itself states that the distributed grains are
oriented through cold rolling process, which gives you
minimized losses.
As the CRGO material having low loss values, these material
is universally accepted to design the Core Structure of the
Transformers, in which losses play a vital role.
CRNO - It is Cold rolled non grain oriented, that means in
this the grains are distributed and not oriented in the
soecific structure.
this process doesn't cause to minimise the loss, and hence
these are having high loss comparitively with CRGO.
These material always finds the application to design the
core structure of any electrical equipment, in which losses
are not concerned to a greater extent.
