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!
Very nicely explained Sir. Thankyou
2:33 each n/w develops a voltage simultaneously at the respective terminals of the interrupter
Great help brother
Thanks for the great explanation!
good Gaurav.keep it up
Thanks
Thanks for the good explanation
Good explanation
Thanks and welcome
Very good. Thanks 🙏
Great Explanation :)
Glad it helped!

This TRV exists for only a few microseconds after which the Normal frequency voltage
Is established
In EHV transmission line circuits TRV oscillations are typically few khz. That makes TRV last like 1000 microsec.
Sir.....pl post the video related to selection value of resistor , capacitor, inductor for circuit designs.

Insightful
Thanks. Do share 😊

Question: The trapped voltages between the source & the load/consumer comes from Xl and Xc in the transmission lines?Great vid!
Yes
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
Kindly make a video on UPS
Where trv occurs more. Is it at low capacitance system
The load type is the main reason for TRV, specially inductive loads.
How to calculate RRRV
Difference between TRV and ferroresonance
Please talk about X/R ratio!!!!!!
Sir please make a video on High speed earth in GIS
Sir, please tale me what is trap charger, how it's come to both link,
Tq sir love this video
Thank you 😊 do share and subscribe 😇
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.
Reignion and restrike
5:10 Arcing medium is trying to regain its insulating properties
Arc plasma containing conducting ions restablishes current
2:20 Trapped charges on each side will try to redistribute
*Each NETWORK
3:00 TRV has several times higher frequency than normal system 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
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
Viedo:Surge protection on LT
This TRV is more across the first pole to clear the
Fault
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
