Even after watching old videos multiple times after months, there are still lots of HELPFUL content. Thank you, Gaurav J!
The protection accuracy is also depends on magnitude of short circuit current. For example the 5P20 shows the accuracy of 5 % at 20 times rated current at primary. Therefore in my idea just saying 5P protection core is not accurate. The maximum short circuit current should be stated as well.
Very good. Thanks Sir 🙏🙏🙏
Greetings from Pakistan sir you are providing valuable content. Keep it growing
Second viewer from Nepal , please keep making as like this video sir
Great job man keep it up .... I highly appreciate your effort. Your vedios are very helpful.. Like you from Bengal
Thank you! Do share !
Thank you sir

Sir please substation equipment testing par ek course bnaiye. Kyo jo v experience log hi interview me testing se questions pucha jata hai or ham log operation vale hai answer nhi kar pate. Sir plz ek aisa course bnaiye ko jo testing nahi v kiya hai vo ekdam har question ka answer de sake.
Good content 🙌🏻. Can you please do a video about relay coordinations Sir
Saturation of CT may also please be elaborated.
Plz make video on surge arrestor name plate,
Sir please make a video about negative sequence protection schemes
Difference between DRY AND WET transformer .
I WAS ASKED IN AN INTERVIEW AND I AM NOT SURE OF THE ANSWER
Q-WHAT WILL HAPPEN IF I CONNECT A PT IN SERIES TO THE LINE ? (SPECIFICALLY ASKED ME ABOUT THE HEALTH HAMPERING)
ANS- THE PT WINDINGS WILL BURN , INSULATIONS WOULD DAMAGE , BECAUSE PT IS A STEP DOWN TRANSFORMER , WHEN PUT IN SERIES TO LINE , THE PRIMARY CURRENT IS THE LINE CURRENT WHICH IS QUITE HIGH AS COMPARED TO THE CASE WHERE PT IS PUT IN SERIES , THE SECONDARY CURRENT WOULD BE MUCH HIGHER , AS PT WOULD HAVE SECONDARY OPEN , WHEN HUGE CURRENT FLOWS THROUGH THE OPEN CKT , IT CAN DAMAGE THE VOLTMETER AS WELL AS HUGE BURNOUT IS POSSIBLE FOR ITS HIGH CURRENT
SIR IF YOU COULD CHECK MY ANS AND RECTIFY ME , OR ADD SOME POINTS TO MY REASONING I WILL BE GRATEFUL
Thank you sir
