Sir here in this setting whts the mean of time setting multiplayer is 1 available why it's value is 1? Please make full video so same in setting group all setting meaning can understand like operation is On out of 3 and Tsm like that..
Wrong calculation. If transformer full load has 220Amp. And u are setting,CT ratio-400 for primary and 5 amp for secondary. Then In-400Amp. If you are putting low stage full load overcurrent tripping setting,it should be 85% of your full load current. It simply means it should be set as a 0.85*In.
@@ElectricalandElectronictech sir I am justing giving example for low stage. If you FLC is 220 Amp. U can set 0.5*In. So it will trip on 200A for low stage overcurrent.
Friend ,you are right as per your Calculation ,if CT ratio 400/1 amp.you can set 0.5 for 200 amp tripping. But if CT ratio 400/5 amp you should set 2.5 for 200 amp, 2.75 for 220 amp.

agAr 300/1 ki ct hai tu phr ka setting ho gi
Thanks for it.
What is IN???I think you had done wrong calculation. It shoud be 0.55*IN..where IN is I nominal you can take IN 400 or 5 amp..Pls explain...
Yes ,he is wrong. You are absolutely right.
In should be ct primary
Wrong calculation.
If transformer full load has 220Amp.
And u are setting,CT ratio-400 for primary and 5 amp for secondary.
Then In-400Amp.
If you are putting low stage full load overcurrent tripping setting,it should be 85% of your full load current.
It simply means it should be set as a 0.85*In.
If you set 0.85.the relay trip at 340 amp(0.85 x400)
But your full load current 220amp.
Then how to relay protect your load
@@ElectricalandElectronictech sir I am justing giving example for low stage. If you FLC is 220 Amp. U can set 0.5*In.
So it will trip on 200A for low stage overcurrent.
Friend ,you are right as per your Calculation ,if CT ratio 400/1 amp.you can set 0.5 for 200 amp tripping.
But if CT ratio 400/5 amp you should set 2.5 for 200 amp, 2.75 for 220 amp.
