[@mohammadpathan4668]

can we use LV side setting instead of HV side O/C setting in this REF 615 relay ?

[@ElectricalandElectronictech]

Yes, you can set L. T side, but C. T input taken from L. T side

[@panditvishal5451]

Please provide fault current calculation for jvs relay..

Sir, I>,I>> Kaisa set karsakte hy .

[@poojamishra024]

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...

[@debdattaG]

Yes ,he is wrong. You are absolutely right.

[@orkhanmirishli1631]

In should be ct primary

[@orkhanmirishli1631]

What is ln inside relay? Ct primari?

[@aitazazahsanofficial]

agAr 300/1 ki ct hai tu phr ka setting ho gi

[@rahulsahane6878]

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]

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

[@rahulsahane6878]

@@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.

[@ElectricalandElectronictech]

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.
