Description : Explain HRGO and CRGO. State benefits of CRGO for manufacturing of core. 

Last Answer :  i) HRGO ( Hot -rolled grain oriented steel):  * To minimize the size of machine flux density should be high with small magneto motive force (MMF). Due to this iron loss will ... percentage of silicon which in turn increases the resistance compared to regular steel which reduces eddy currents. 

Description : Distinguish between HRGO and CRGO on any four points.

Last Answer : HRGO CRGO Hot rolled grain oriented steel Cold rolled grain oriented steel Grain orientation is obtained by hot rolling to obtain soft steel to facilitates machining process. Grain orientation ... etc. Used in Transformer core, Machine cores etc. Less cost More cost

Description : Which of the following is the advantage of using CRGO steel in transformers? A) High magnetic flux density B) Low permeability C) Both A and B D) None of these

Last Answer : It definitely High Magnetic Flux Density since a crgo steel has always a more around 3% of silicon proportion among the remaining ferrite which make cold rolled grain oriented steel having high flux magnetic ... for more about the crgo core you can learn here https://nicoreindia.com/crgo-core/
