Distance relay manually calculation | impedance calculation for transmission line |Zone calculation

we are going to see how to test distance protection calculation manually
For that i have taken all sample value for calculation
Buy using this we can able to find the
Zone calculation for following characteristic
Quadrilateral characteristic
Impedance characteristic
mho characteristic.

It is very easy method to find the distance calculation for all zone, such as zone 1, zone 2, zone 3 and zone 4.
and also the calculation is done by step by step for easy understanding

Really, your contribution is matchless. A big salute to you. 🙏

[mdnadeemhussainansari]

Thank you sir to contribute towards electrical engineering community

[nitinkamath.A]

👌👍 more information & case studies required, testing information required

[liewts]

Hi Berani Tech, thank you for your contribution. May I highlight that the impedance ratio should be VTratio/CTratio = (220k/110 )/(1000/1)=2 not 0.45 in this case. As for the calculated zone impedance unit, they should be in Ω not Ω/km. Hope this can be helpful.

Thank you for the information sir 👍 Very useful 💜💜

Thanks bro always waiting for your video

Hi, thanks for share your knowledge.
pd, there's a mistake in the Z2 (Ph-Ph) R1 calculation: It is 3.62 Ohms, not 3.14 Ohms

sir plz guide how to draw quadratic curve in omicron using the calculated setting

[sarojiniperumalla]

Thank you sir, execellent informatiom

[ImranKhan-nuxw]

Hi dear
How the setting is used for quadralatic characristic relay ??

[Abhishekmishra-wylp]

Please do make Video for differential & EF protection also.

[chandbasha]

sir, how to do the Alstom P442 relay settings calaculations for radial feeder having length and trf percentage impeadence.then how we need to do the settings...pls guide me..thanks

[pratiksharma]

what we will do if there is a transformer between the bus.. and busses have different voltage level

[furqanazam]

awesome... kindly make videos on Micom and Siemens relays setting calculations

[techeducation]

Thank you so much sharing your knowledge it's very helpful for those who are starting there career in protection field like me.
Sir, small one doubt, Z=CT/VT *100%.
So, 1000/220×100%
=4.5/100
=0.045
But in video it's 0.45 you taken. Please explain sir??

[ketsanasana]

Hi sir. Have you had any experience in putting wrong impedance value when setting relay protection? In my country don’t have impedance measurement device, so I only get the impedance value from the Digsilent program. Can you explain the best way to me?

[jeganathanvaradarajan]

sir one doubt this calculation is common for all relays

[snehakushwaha]

ye calculation kis relay ke liye h..????

[ranjansahu]

Very good explanation sir... But I can't understand how the ct/vt ratios become.. 0.45... it's 1000/220kv/110... It's 0.5 na..

Why -ve sequence is not considered.. plz sir explain

Good work but you are covering the board.
