Plz make vdo on motor protection of ht motor with under voltage over voltage, differential protection & also its related relay like abb spam spaj spau type with practical
Very nice explanation. Can you please explain HV motor differential relay connected and the source side power cable circuit. What will the consequence in the differential CT (87)
I have already uploaded a video on transformer relay co ordination setting. That covers majority of trafo protection.. ref protection setting is already uploaded. Remaining protection is differential, which I shall upload later... I have plant to upload all protection settings. Please stay tuned, and share my videos
Yes, i have plan for making such video. I have already uploaded setting example for over current and earth fault protection. You can check that. Give me some time. I will upload entire protection system
these motors are protected as per type 2 co ordination. basically it has mccb, with on off contactor and a bimetallic thermal over load relay. mccb gives Protection against sc and e/f fault, bimetallic o/l relay gives Protection against over load. contactor is used for on off the motor... ratings of these are dependent upon the motor rating and it is available in type 2 co ordination chart. you can find it on internet. manufacturer gives the chart
Not over current but overload relay. Those are not same. Now coming to your questions. Suppose a motor van be loaded to maximum 80% of its rating. Now during some time it is running at 50% load. It happens often in plant. Now in that time if the voltage falls then there won't be significant overload. But under voltage... That is why separate relay is considered
@@electricaltechnologyandind5335 if i understood correctly if we keep overload realy even though in under voltages also our system will not damage but only it's steady state performance will be Afftected.
Nice explanation kindly make videos on testing of electrical equipments like routine,type and site acceptance tests of (cable,transformer,generator,motors,switchgear mv,lv,hv)
to be very honest i am professionally a design engineer. so i don't have any exposure on testing. however i shall try to collect data so that i can make video....
Please explain, how many relays can be connected through one CT, are all connected on the same core, each relay has different application so how are they done?.
Actually modern day numerical relays take current input from one core, and analyze for different application. Only differential protection is connected through ps class CT
ELECTRICAL TECHNOLOGY and INDUSTRIAL PRACTICE Much appreciated, I'd like to get you advise, I can find a lot of materials giving the principles, but practically when I hardly can find any book or reference explaining the calculations or the design steps. any recommendation for a book shows the calculations in details.
Really a exposure to industrial experience...Good explanation Upload some videos on protection of transformers and feeders w.r.t industrial practice as you are doing. Thank You
First of all spelling is wrong!!!!! Secondly vai itna to akal hai ki fart marta to usse edit karke nikal deta!!!!!! Those have been microphone sound.. so relax...

Thankyou very much, so helpful for struggling students. You litterally save my grades, big thankyou..
this guy big up so nice in explaining detailed thanks sir make video on protection relay testing
Plz make vdo on motor protection of ht motor with under voltage over voltage, differential protection & also its related relay like abb spam spaj spau type with practical
very impressive it helps us a lot in doing the above practically in the Gulf.
Thanks for information will you please make a video on the calculation of the motor protection.
Thank you so much ... Can you make vedio REM601 motor protection relay and it's fuctions.
Very Informative Video:)
Very nice explanation. Can you please explain HV motor differential relay connected and the source side power cable circuit. What will the consequence in the differential CT (87)
Thank u very much. your vedio is very much understandable.
Can u make a vedio on motor and transformer protection setting calculation.
I have already uploaded a video on transformer relay co ordination setting. That covers majority of trafo protection.. ref protection setting is already uploaded. Remaining protection is differential, which I shall upload later... I have plant to upload all protection settings. Please stay tuned, and share my videos
Nice video sir ..
What is use of negative sequence protection in motor
Diff between 50L/R and 50 relay?
Very good. Thanks 🙏🙏🙏🙏🙏
Please make a video on "Motor protection relay Settings"...i.e., what should be the values to be set?
Instrument type earth fault protection ke bare mein btayein?? How dc current function in that??
Please I need a video on how to come up with motor control circuit
It's an very knowledgeable .
My request to you that please take a one example of settings acording to motor name plate....
Yes, i have plan for making such video. I have already uploaded setting example for over current and earth fault protection. You can check that. Give me some time. I will upload entire protection system
Please make videos on Vaccum circuit breakers for HT motors and their protection
Can you please explain it with a motor example how the different protection setting are done.
See my latest video. You will get some idea.
thank you very much for all your efforts and we need more deitailed about any protection of induction motor and how to calculate and setting
Appreciate your video. Can you cover transfo,generator, line differential protection also
Easy to understand pls make video for generator and transformer protection same way of explanation
Very crisp and clear,, good u have good knowledge keep improving...
Pump well vfd maintaince and motor maintenance one video on that topic
Great video.
Please upload the protection relay settings of LT induction motor beyond 70 KW

please share Generator protection and excitation Vedio also
Your vdo are superb 👌👌👌
Nice explanation...
Can you please make a tutorial on ecs system
Thanks फ़ॉर nice vedio sir transformer प्रोटेक्शन पर भी एक vedio बनाये।
Can you explain the zero sequence ,positive sequence and negative sequence in context to synchronous machine
Thanks alot for teaching me about sef
Sir u said under voltage relay-27 draws more current so over current relay is enough no y we r using another relay for it.
Not over current but overload relay. Those are not same. Now coming to your questions. Suppose a motor van be loaded to maximum 80% of its rating. Now during some time it is running at 50% load. It happens often in plant. Now in that time if the voltage falls then there won't be significant overload. But under voltage... That is why separate relay is considered

Super sir
Thank you .
But what about the differential relay 87 M .one CT before motor and the other after motor where install it
At motor terminal box. The other one at switchgear panel
@@electricaltechnologyandind5335 thank you very much
Kindly upload some video on generator excitation and on AVR
Why 50L/R and 50 (Instantaneous Over current) both required for motor?? How you will distinguish these to condition??
Current >=2*motol flc is detected by 50lr, and for current higher than 7 times is detected by 50
please make video for big motor protection for 6.6 kV avobe rating 1 MW
Please explain, how many relays can be connected through one CT, are all connected on the same core, each relay has different application so how are they done?.
Actually modern day numerical relays take current input from one core, and analyze for different application. Only differential protection is connected through ps class CT
@@electricaltechnologyandind5335 Thanks
Explain about fault current limitation by using series transformer
There is a video.. purpose of lighting transformer
exellent work thanx bro
Awesome video, Can you please do video for the relays settings calculation for the motors protection such as 27,37,46
Ok I shall try... I am receiving lots of comments, and i shall definitely try to make video on all the topics
ELECTRICAL TECHNOLOGY and INDUSTRIAL PRACTICE Much appreciated, I'd like to get you advise, I can find a lot of materials giving the principles, but practically when I hardly can find any book or reference explaining the calculations or the design steps. any recommendation for a book shows the calculations in details.
Pls explain motor hot and cold curve
Good Video
If we put 50 , it is instantaneous , but the starting current will be 6 to 7 times of the rated current , so it will trip , ??
please make video on GPR calculations
Thanks 🙏
Thanks a lot..
Thankyou bro
Please make on co ordination
Nice
Try to upload generator capability curve for supercritical generator
Thanks 😘😘😘😘😊😊☺️☺️
it can also occur problem during its start how to solve its problem
Which can also create problem?
Bhai apne like this kehte samay kya kia 1:16 pr
Really a exposure to industrial experience...Good explanation
Upload some videos on protection of transformers and feeders w.r.t industrial practice as you are doing.
Thank You
Thank you so much... Yes I have plan to update more videos on other machine protection, please stay tuned
sir hindi and English dono mi batana chaheyi olr
,,👍👍👍
where is the 51 & the 51N?
Motor has no need of 51 and 51n inverse time relay should be avpided for motors
Hindi please sir
Hindi me video banaeA
Vdo me bhi fat mar diya 😛
First of all spelling is wrong!!!!! Secondly vai itna to akal hai ki fart marta to usse edit karke nikal deta!!!!!! Those have been microphone sound.. so relax...
