How did you choose the pick up current 1.05 ? As I know, it suppose to be the normal load current * 1.20 , which is huge.
Thanks

Is there a sequence in which we can watch these videos? Currently even though each video is good quality, unable to co-relate with any particular SLD

[@SmartEducare]

You can start from this video for relay setting and protection coordination:

Isn't it true that if ( pick up current * ratio CT ), then the current seen by the relay will exceed CT? make CT burn.

[@SmartEducare]

That's why CT selection to be done properly to avoid CT saturation..

How you determine TMS is 0.16 s

[@SmartEducare]

TMS will be selected based on upstream and downstream protection coordination
