3:21 waveform n TRV depends on 4 factors 1) condition at which the contacts are separating ???? 2) Type of fault 3) Characterstics of Network connection ???? 4) switching arrangement
Hi, thanks for the excellent videos. My understanding of the 'trapped' charges in the lines (after the breakers have been opened) is due to the line inductance and capacitance. Normally the line is mostly inductive so the energy is stored in the inductive element (E = ½ * L * I²) and when the load is disconnected the energy becomes stored in line capacitance (E = ½ × C × V²), hence needs to be discharged via earthing switches. Is this correct? Could you please make a video about these trapped charges and the effects they have on arcing? Many thanks!
2:33 each n/w develops a voltage simultaneously at the respective terminals of the interrupter
Very nicely explained Sir. Thankyou
good Gaurav.keep it up
Thanks
Great Explanation :)
Glad it helped!
Thanks for the great explanation!
Question: The trapped voltages between the source & the load/consumer comes from Xl and Xc in the transmission lines?Great vid!
Yes
Great help brother
Thanks for the good explanation

This TRV exists for only a few microseconds after which the Normal frequency voltage
Is established
Good explanation
Thanks and welcome
Sir please makes videos on different circuit breaker mechanisms - siemens, abb( hpa ,hca,vd4),areva,cgl - spring mechanism . Please
Nowadays, all manufacturers use the same mechanism i.e. spring - spring
Please elaborate the mechanism how its working if animation is possible then it will be awesome.
Yes sir plz make a video on mechanism
In EHV transmission line circuits TRV oscillations are typically few khz. That makes TRV last like 1000 microsec.
Where trv occurs more. Is it at low capacitance system
Sir.....pl post the video related to selection value of resistor , capacitor, inductor for circuit designs.
+1
Why in circuit breaker capacitive line charging breaking current is mentioned but not inductive current breaking
You are awesome
2:20 Trapped charges on each side will try to redistribute
*Each NETWORK
Very good. Thanks 🙏

5:10 Arcing medium is trying to regain its insulating properties
How to calculate RRRV
Insightful
Thanks. Do share 😊
Kindly make a video on UPS
Sir, please tale me what is trap charger, how it's come to both link,
First view sir I always support you 🙏🙏
But I have a recommendation create one more channel with Hindi Language except technical terms
❤️❤️
No, continue to speak english to hit a wider audience.
Sir please make a video on High speed earth in GIS
3:00 TRV has several times higher frequency than normal system voltage
Please talk about X/R ratio!!!!!!
Arc plasma containing conducting ions restablishes current

Tq sir love this video
Thank you 😊 do share and subscribe 😇
Reignion and restrike
5:40 if rate of rise of recovery voltage is higher than the
Speed of the insulating medium
Breaker will fail to clear the fault
The load type is the main reason for TRV, specially inductive loads.
Race is there conducting state and insulating state
Fast changing voltages are there
Interrupter should be able to handle these fast changing voltages
*fast arising recovery voltage
Sir what about CB drawing course?
It is coming soon. You can get more information about it on courses.theelectricalguy.in
It can cause reigniting and rearcing
4:50 break of the system
This TRV is more across the first pole to clear the
Fault
