Best video on Trafo differential bias scheme . nice explanation . i hope you will post similar type of videos in future also.

I have become fan of your knowledge and fundamentals. Great job sir....you are a guide of millions of protection engineers...thanks..May you prepare a video on 2nd harmonics testing of restricted earth fault protection and it's requirements...

Great video upon RET670 testing through Omicron test kit (Diff Characteristic). Here some parameters missing to set in relay test kit viz. Idiff >>, Idiff>. If pick up value less than .3,then you have to set accordingly. Also after drawing curve in characteristics, it is not reflecting same as in test module. Here some video skipped. However it has given good reference for testing. If this clarity is given in upcoming videos, it will really help working engineer like me. Thanks for reading my feedback.

[@baranitech1026]

This parameter 100 % will match for RET 620 series. i will try to make more clear and without skipping on next time and thank for your feed back .

Thanks for step by step guide to RET 670 Diff testing through Omicron Test kit specially shot test and search test. Kindly review Bias formulae of ABB RET 670. As per manual, it is mentioned maximum of individual current referred to Primary. please share other make relays Bias formula for preparing exact slope characteristic.

Great Video Sir!!! How can one test line differential relay using the differential operating characteristic module. I have checked and have seen on the protected object that the protected equipment options are only transformer, Generator, Motor and Busbar.

[@baranitech1026]

for line differential we do end to end test on quick CMC . if you want to do on differential char. then you can select generator for line

Here RET615 is taken as relay. For 670 series, correction factor is not required and all values we can change.

[@baranitech1026]

yes it for RET615 and RET620 for calculation part

[@thanhnghean90]

good

[@baranitech1026]

Thanks

[@ibnelkhan]

Dear Sir, You have calculated matching factor, but in testing where have you used matching factor in testing? plz could you explain this, as you have used full load current every time. thanks

[@ibnelkhan]

​@@baranitech1026 I am little bit confused here, sorry for this, But during testing should we inject the current after multiplying it by matching factor? Cz you have only injected calculated full load current, not the one with matching factor.

[@ibnelkhan]

Understood thanks

[@F13TUN]

AT 13min :00 why didi you choose 0 degree for Ip and 210 degree for Is .As i understood we should have opposite angle ie 0 for primary and 180 for secondary to get the sum of vectors =0 .

[@surya-pc7nx]

Dear Dharani can you take this exemple for satisfying matching FACTOR For differential protection. S=25MVA Hv=22kV Lv=6.9kV Hv CT=1600/1 Lv CT=2500/1.

[@ByunJungSicidsky]

Dear Barani During the Omicron slope test, I have a question. For example, to test idff(0.3In) Ibias(0.5In) value, P-L1/L2/L3 and S-L1/L2/L3 current and angle are displayed automatically. Can you please tell me the formula to manually calculate idff(0.3In) Ibias(0.5In) values for P-L1/L2/L3 and S-L1/L2/L3 current values?

Very nice video.. But 1 confusion about CT matching factor, if HV CT Ratio 200/5A and HV FL current 175A. Then matching factor 1÷4.37 or 5÷4.37? Please confirm.

5/4.37

Sir, sir we replaced the 2 phase old CT of 20MVA PTR with new ones and during the stability test we observe double(0.4+0.4=0.8)current in 1phase,, and all the CT secondary polarity is ok, and then we review the relay setting vector group is Dyn5 instead of Dyn11 please explain how vector group of PTR will be affected CT secondary current

[@haiderzafar6200]

For RET615, where are the details entered regarding trafo MVA, hv and Lv voltage rating, vector group etc. I can't seem to find those details in relay.

[@vinayks3131]

For RET615 there is no option to enter Trafo MVA. We use the above showing calcalations. However for 670 series, we don't need correction factor.
