Differential relays:
The differential relay responds to vector difference between two or more similar quantities.
- The differential relay has at least two actuating quantities say I1, I2
- The two or more actuating quantities should be similar i.e. current 1 & current 2.
- The relay responds to the vector difference between two i.e. I1 ~ I2 which includes magnitude and/or phase angle difference.
Differential protection is generally a unit protection. The protected zone is exactly determined by location of CTs. The vector difference is achieved by suitable connection of CT or PT secondaries.
Hurrah, that's what I was seeking for, what a stuff! existing here at this blog, thanks admin of this web page.
