Hi Julius, I am thinking that 24:15 Earth fault protection If it is set only 2 value i.e., threshold and definite time, it should be called as 50G not 51G Unless you select IDMT Characteristic e.g., NINV, VINV or EINV Normal/Very/Extremely Inverse respectively and set time multiplier this will be 51G
great video, thanks for sharing. might be a good idea to include the motor inertia, mechanical load details, run a simulation using Digsilent power factory , and see the performance of the protection setting under various operating scenarios.
Thanks for sharing the valuable information Kindly prepare a vedio on radial feeder setting for distribution system of load 7000kva, full load current 400 amp ,bus voltage 11kv ,CT ratio 400/5 ,low settings,high setting i.e I>,I>>& I>>>
Hello, great video. Where did you get the settings that you show here? For example, the 80% of the short circuit current? Is there any standard for this? Thank you
I think for the 80%, it is related to the setting of undervoltage relay. For industry practice, undervoltage relay setting is being set between 70 % to 80% of the nominal voltage

nice video tutorial sir
Thanks a lot for this great video but how we set IDMT RELAY I mean 51relay second stage
IDMT relay second stage is not being envisage for MV motor feeder relay

I'll consider your request on my future videos, welcome

And for Time of 70% WE Can let 3sec??@@juliussalutan8006
Sir, yung SONDE temperature protection, Anong temperature element po gamit nun same lang po ba sa RTD Pt.?
Yes sir, RTD PT100
