bhai g bahut acha kaam kar rhe ho ...itni specific deapth me jaane wale sirf electrical engineer hai.. jo bahut kam ha aur maximum it sector me kaam kar rhe hai i...so u r doing great job..full support by me any other person watching you.
Thank you sir for such a wonderful session. Your in-depth knowledge of these concepts are reflected in your way of explanation. I am working as a commissioning engineer since last more than five years but today I have understood these concepts in true sense. I hope you will continue to enlighten us with such wonderful session in future also.
What is the estimated duration for carrier sending and receiving echo from other end in case of (1) plcc communication (2) opgw fibre optic communication?. Thanks for your reply.
Yes definitely I will make video on this topic but presently I am trying to finish all aspects of DR Analysis using SIGRA and wavewin. This topic will take some time so expect sone delay on line differential protection. Sorry for the delay. My target is to complete every topic in detail for better understanding.
It may be applied in PUTT scheme also but generally not applied because in PUTT Scheme the carrier is sent with Zone-1 pick-up. Zone-1 reach is only 80% of principal line impedance so in case your fault is nearer to the remote bus then generally these faults comes into Zone-2 and not in Zone-1 and hence in PUTT Scheme these faults are always cleared in Zone-2 time only, even if you have CB OPEN or WEEK INFEED LOGIC..... However, in case of POTT the carrier is sent with Zone-2 and hence all faults anywhere the principal transmission line are cleared instantaneously with CB ECHO and WEEK INFEED LOGIC.
Sir in PO scheme WI Echo logic main.. only z2 pickup hoga to... Left side k z4 v pickup hona chahiye... Then only & gate high hoga aur signal ho left side vejega... Sir pls rectify me..
Yaha par Z4 Pickup nahi balki Reset use kiya hai... Logic gate me Z4 ke input ko invert karke connect kiya hai... Z4 reset isliye lete hain kyonki ham ye ensure kar lete hain ki fault reverse direction me nahi hai.... Iske baad do condition bachegi ya to relay forward direction me pickup hogi ya relay pickup hi nahi hogi... Agar relay forward direction me pickup hogi to Z2 ke through carrier send hoga aur agar relay pickup hi nahi hui to Z4 reset condition ke through carrier send hogi (provided WEI logic implemented ho scheme me)... Video ko 36 minutes ke time frame ke baad dekhiye clear ho jayega

I saw lot of videos, but this video only cleared all my doubts on Distance protection schemes. clear explanation.

Thanks for your reply.
सर आप बहुत ही अच्छे से बताते है, सर ट्रांसफार्मर protections के बारे में बताये।
अभी बस 1-2 टॉपिक और बचे हुए हैं लाइन के प्रोटेक्शन का और उसके बाद ट्रांसफार्मर प्रोटेक्शन स्टार्ट करेंगे। इस सप्ताहांत में ट्रांसफार्मर आ जाएगा।

Hi sir
Yee permissive under reaching and permissive overreacting internal trip me kya difference hai
Sir, kindly make a video on detail working principle of battery charger available in grid substation and trouble shooting of it.
very nice explaination sir...!!
Thank You for your valuable feedback.
Very nice explanation. Thank u sir

Ultimate sir 🙏🙏
Thanks for watching Pradeep Jee. New video will be uploaded shortly. Stay tuned.
@LIGHTNING MINDS WHY SHORT T/M LINE IS NOT USED IN QUADRILATERAL CHARACTERSTICS SIR IF MHO CHARACTERSTICS HAVE LIMITED DUE TO FAULT RESISTANCE
Thanks sir
Thank you for watching the video
Please make a video on quadrilateral characteristics with examples and calculations.
Ok... I will upload a detailed video on calculation of different parameters of quadrilateral characteristics
Sir make a video on Bus Bar protection individually on DMT and one and half CB scheme
Ok Noted.... I will upload video on this topic shortly
Thanks for the lecture Sir.
Can the CB echo or weak infeed logic be applied for PUTT scheme?
If not, why Sir.
It may be applied in PUTT scheme also but generally not applied because in PUTT Scheme the carrier is sent with Zone-1 pick-up.
