- Transformer Differential Relay testing and how to create slope on Omicron kit for RET 620 relay.
and also show how to create slope on omicron kit.
Transformer details are
SN [KVA] = 25000
V1N [KV] = 33KV
V2N[KV] = 6.9KV
Zk[%] = 10.00
Vector Group = Dyn11
CT-HV = 600/1A
CT-LV=2500/1A
Relay setting are
ID low set = 30%
ID high set = 1200%
Slope 1 = 30%
End section 2 = 150 %
Slope 2 = 100%
Note for RET Abb relay end section 1 is 50%.
in this video you can able to see following test
Pickup test
Stability test
Instability test
Slope test.
a.shot test
b.search test
Dear sir, thank you for sharing your knowledge, I think the world would be a better place with people like you.
thank you and most welcome
Excellent, I searched for those videos alot but not found by this details way, Thanks alot
your most welcome
Best video on Trafo differential bias scheme . nice explanation . i hope you will post similar type of videos in future also.
really awesome content bro.. can't thank you enough!
Great Video bro.... shows your in-depth knowledge on the subject... hope for more great videos...
Very useful video, Thanks from your efforts
Simply Superb. Well done.
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...
i will try to make
Awesome explanation...if possible request you to pl. Add link in description every other video you'd mentioned in narration next time.
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.
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 .
Great lecture... sir please make video on LINE DISTANCE PROTECTION with zone calculation.
Thank you for your valuable upload .it's very useful for me.kindly upload harmonics test and REF test .as well as RED670 all test
@@baranitech1026 i am waiting for your next upload for RED670 relay testing
Nice video, good to value addition
thank and welcome
Hi, I like your video. Thanks
Thank you too
Really thanks for knowledge
welcome
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.
Usefull
thanks and welcome
Very useful brother...,
Thank you very much
Excellent Sir..
thank you
You are great sir❤
thank you very much
Thanks you
Very good
welcome
Please give video for phrase angle compensation video related to vector grp.
Very good. Thanks 🙏🙏🙏🙏🙏🙏
welcome most
Please Sir explain Generator Protection like Differential, Reverse Power, Stator Fault, Overexcitation etc.

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.
good
Thanks
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.
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
How to test differential protection of a three winding transformer.... Please explain
good video. can you teach us about abb pcm / siemens digsi software configuration along with required driver ?
@@baranitech1026 thanks bro ... good work ... you know ssooo many things :)
Do you have any video for step by step Low Impedance REF Transformer Protection Setting Calculation include?

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
i will make one video related to your questions.
Can you tell me the topic name for cal the slope
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 .
could you please also provide the testing of siemens 7UT trafo Diff relays
yes
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
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.
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.
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?
ruclips.net/video/585TDCgAki4/видео.html
Here RET615 is taken as relay. For 670 series, correction factor is not required and all values we can change.
yes it for RET615 and RET620 for calculation part
Hello, how can I get the bias calculation? Can you please share any link or manual about it?

Hi sir
really super
i have doubt about HOW to find out single phase pick up?
Dyn11 for HV and LV
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
@@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.
Understood thanks
bias current formula for RET670?
(I1+i2)/2
Omicron differential protection parameter Primary current you to us Transformer FLA but if i will put CT current i will happen.pls tell me
@@baranitech1026 maximum site i have finish by CT ratio that time i am not getting any problem
I think RET670 match factor not available in parameter
yes
@@baranitech1026 but how to relay matching that much of current
how to find es3 and y3 values ?

please follow video step by step it will change.

Sir please don't add music in your video it disturbs...
Details of this vector when we are getting boss,
@@baranitech1026 okay boss
Sir how to get value for Id and Ib value at stabilty and unstable condition
I1-I2 is Id and IB = I1+I2 /2 is for all condition
Thank you sir!!!
Music sounds are irritating, please filter it out, no one prefers to listen music while understanding differential protection.
my new video i am not merging sound. sorry for this.
Music between class was so annoying
i have stop mixing music but sorry for this video
Music idea is very worst. For excellent topic
sorry it was avoided in future.
the idea of putting music in between is worst..... this is such a comprehensive topic and one cannot be short of words to put music instead. plus it shatter the tempo and focus...... it's just irritating and please try to clear your accent and pronunciation wofsome words......
@@baranitech1026 I'm also in relay testing and came across your channel and thought to watch it.
