Lecture 26 Protection of Transformers-I

This lecture starts with types of internal faults occurring in the transformer. Then, it explains the operation of Buchholz relay for incipient fault. It also describes different types of internal fault protection technique such as overcurrent protection, restricted earth fault protection and differential protection. Further, it explains circulating current differential protection and its problems.

Sir if it reduced by √3 times it would be. 578
But it's. 707 means reduced by √2 times that is. 707.

18:23 ... Necessity of Restricted earth fault protection

[@AliRaza-iq5dr]

From Lahore really nice wordings about protection of transformers.

[@pradipgajbhiye6910]

Sir How much Percentage of winding protection by Differential protection and REF protection please

[@madhavrabinbipin2116]

restricted earth fault explained best here

[@shahilkhan5433]

Thank you sir.
For this great class

[@deepakkokare7445]

Sir,
You interchanged delta winding and star winding during restricted earth fault protection explanation..

[@surendrakverma555]

Very good lecture Sir . Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@Nivupedia]

Very nice illustration 👍

[@ohgoditsjames94]

Think you made an error 14:00, HV side for distribution 11kV to 415V transformers is almost always Delta and the LV side is Star, or at least here in the UK they are.

I need 1 ph and 3 ph pickup calculations differential protection

[@santanu6763]
