Sir we also use percentage differential protection in transformer protection scheme. So what is the difference between differential and percentage differential protection? which one should be prefer for transformer protection.
Sir, can we differentiate the two relay saying that Buchholz relay is useful during overload and differential protection is useful during any leakage current in the protected zone?
Good video. Differential protection is mandatory above 10MVA. Is it possible that in under construction power sub station, the Differential operates even if transformer is not connected to power lines 😊
Differential Relay Transformer protection: For internal fault protection of transformer ratings of 5MVA and above (We use both DR and Buchholz relay) Below 5MVA transformer we only use Buchholz relay. Incase internal fault occurs in the transformer but not in the oil such as faults in the transformer bushings then Buchholz relay will fail to work so inorder to protect against such internal faults we use differential protection. Differential relay has very less response time as compared to Buchholz relay. Differential relay only operates in a zone of protection and cannot operate in outaide the zone of protection. It is a specialize mode of protection and can also be use in generators and motors.
Hi sir very informative video. Tq so much but Mera ak question hy sir BDV test kab karana hy kyam karana hy thoda baatyeana sir. Our oil filterzatio bi kab karana hy
Sir 500mva ke Trafo mei ager oil ke ander koi fault hota hai to isko differential relay protect karega ya buchholz relay protect karega , kyunki di differential relay ka response time bahut kam hota hai please reply.
Sir ek interview mai mera se pucha tha relay series mai lagate hai ya parallel...sir is per ek video bana do ya yahi comment mai bata dijiye... Thank you.
Hemant, over current relay ki setting par Maine video banaya hai.. ACB ki settings pe bhi video banaya hai usme aapko overload, short circuit, instantaneous and ground fault ki settings mil jaegi..
Sir agar 5MVA SE Kam transformers me bushings me fault ajaey ya agar oil k area SE bahir fault ajaey to uska kesy pata chalega q k less than 5MVA me to differential relay nhi hota?
I have made video on restricted earth fault protection. I have also made video on how to read drawings of restricted earth fault. Kindly watch that video.
Thanks sir.aapki video dekhkar bhut kuchh seekhne ko milta h.easy explain and valuable
Because of u i got the job❤

Plz 220kv ke busbar ka low impedance and high impedance busbar protection scheme, wiring/ connection bata dijiye. Aap bahut badiya explain karte hain
👌👍bhuthi badhiya information thanks 👌🙏
Informative
Video , thanks sir

Sir chote transformer ke bushing me fault hota he to konsa relay operate hoga
Good video. Differential protection is mandatory above 10MVA.
Is it possible that in under construction power sub station, the Differential operates even if transformer is not connected to power lines 😊
सिर्फ कामकी बात नो बकवास 👌👌👍👍
All relay ko reset kassa karna prv bucl... And differ.. Relay or self decision at the spot
Informative!!
Sir, please make a video on braking of Induction Motor.
Thank you
Very nice explanation
Thank you Aditya...
Sir, Please can u explain the power & control wiring diagram whether the motor runs on DSC & Feeder side

Sir ek interview mai mera se pucha tha relay series mai lagate hai ya parallel...sir is per ek video bana do ya yahi comment mai bata dijiye...
Thank you.
Thank you so much sir for this vedio
Thank you very much sir
Sirji.....Earthing and neutral ka RYB k sath sequence kya hota h.... Transmission nd distribution line m
Well explained.
Thank you...
Thanks sir..
Please simocode related video banaye...
sir please...make a video on micom P122 Relay testing procedure..
and also make a video on s/s switchgear working procedure....
Sir differential,MRG, eathfault and overcurrent relay ki settings kitne pr rakhi jati hai please ej video bnaiye
Hemant, over current relay ki setting par Maine video banaya hai..
ACB ki settings pe bhi video banaya hai usme aapko overload, short circuit, instantaneous and ground fault ki settings mil jaegi..
Feeder protection or Differential Protection Relay ki settings kitni honi chahiye uspe video banaye
@@electricalwithabhishekjoshiyes sir
Superb sir
very good lecture but it did not provide how differentia relay works through cct diagramme

Sir agar 5MVA SE Kam transformers me bushings me fault ajaey ya agar oil k area SE bahir fault ajaey to uska kesy pata chalega q k less than 5MVA me to differential relay nhi hota?
Sir line distance protection ka detailed video banaiye
Sir please make video on types of electrical loads
Can you make a video regarding feeder protection relay
999+1 = 1k like completed
Sir im job in getco there are 10 MVA x'mer in bucholz relay used
Please make a video subject on MICOM..
Sir make a video on SIMOCODE
Okay Akash..
Sir plz electrical engg field se ache company ke liye bhi video de plz bahut jarurat hai job ki plz🙏
Aapko kaise video chahiye??
Sir Vedio on thermal power plant maintenance
What is a prv relay working oprt and reset with prectal
Sir please can you explain about working principle of induction furnace ?

Brother humey Siemens ki 7sj66 ki complete setting k bare mein batay
Thank you
Sir pls upload video on overload and earth fault relay
Harsh, kindly watch Playlist of switchgear and protection. Waha sab mil jaega..
Sir why we use PRD if there is already a gas operated buchholz relay present?
Buchholz relay will not release pressure from the transformer tank.
Thnks sirji
Most welcome Pankaj..
Namaskar sir ji
How bushings short circuit protection will be performed in low power transformers.
If we don't use differential protection in low power transformers
Good sir
