Sir please provide complete power systems. These vedios are very helpful to me, thanks a lot sir
Thanks for the reply sir
Sir, in indian 33kv system (earthing by grounding transformer) why 42 kv class LIGHTNING ARRESTEE used ? Whearas in 132 kv system ( effective grounding) 120 KV class LIGHTNING ARRESTER USED ?
sir how there is no arcing grounds in this case. here still there is fault current flowing through the neutral and if the fault is cleared there will be change in inductive current from If to Icb , hence causing large voltage across the capacitor and thus arc restrikes. so how does this grounding prevent arc to restrike
Effectively solide grounding provide by
1 rod
2 grid
3 strip
Correct ans sir please respond
sir,magnitude of sum of capacitive currents and and fault current are may not be equal , then how it will be
cancels each other?
for domestic supply in India , which type of earthing system is used, sir?
Sir pls make a video on different types of ckt breakers.. For exam point of view
@@lecturesinelectricaleng thanks for replying immediately
here little doubt rise ..regarding inductive circuit ...how it create there ,due that fault current lag ,capacitive fault current lead both are 180 so nullify...inductive circuit concept little doubt ..pls clarify sir ? or some one... thanks
Sir why current is more than the case of isolated neutral?
Not clear why only the voltage range is 2.2KV to 33KV for solid grounding, Thanks
sir Protection and loadflow analysis bhi cover kariye
See at 2x
Dear Sir , Can I have your email id, I have a query regarding Reactive power flow, I hope you can help me.?
