2:33 each n/w develops a voltage simultaneously at the respective terminals of the interrupter

[@saurabhshrivastava12]

Thanks for the great explanation!

[@ofentsebethel9112]

Thanks for the good explanation

[@surendrakverma555]

Very good. Thanks 🙏

[@aneestec7425]

Great help brother

How to calculate RRRV

[@arbabimran388]

good Gaurav.keep it up

[@GauravJ]

Thanks

[@MrHdave]

Great Explanation :)

[@GauravJ]

Glad it helped!

[@patrickmusonda-ll2jv]

Good explanation

[@GauravJ]

Thanks and welcome

[@ohgoditsjames94]

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!

[@imeprezime1285]

In EHV transmission line circuits TRV oscillations are typically few khz. That makes TRV last like 1000 microsec.

[@donberg01]

Question: The trapped voltages between the source & the load/consumer comes from Xl and Xc in the transmission lines?Great vid!

[@GauravJ]

Yes

[@srinivasansridhar8832]

Where trv occurs more. Is it at low capacitance system

[@abdulmoizzghauri838]

Insightful

[@GauravJ]

Thanks. Do share 😊

[@rupaliranaleaderdevotee]

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

[@rupaliranaleaderdevotee]

This TRV exists for only a few microseconds after which the Normal frequency voltage

[@rupaliranaleaderdevotee]

Is established

[@moumitagorain3492]

Sir please makes videos on different circuit breaker mechanisms - siemens, abb( hpa ,hca,vd4),areva,cgl - spring mechanism . Please

[@GauravJ]

Nowadays, all manufacturers use the same mechanism i.e. spring - spring

[@moumitagorain3492]

Please elaborate the mechanism how its working if animation is possible then it will be awesome.

[@sanjeevyadavec]

Yes sir plz make a video on mechanism

[@rupaliranaleaderdevotee]

Arc plasma containing conducting ions restablishes current

[@SABARI-nv9kf]

Sir.....pl post the video related to selection value of resistor , capacitor, inductor for circuit designs.

Reignion and restrike

[@hanial-shadadi9122]

The load type is the main reason for TRV, specially inductive loads.

Kindly make a video on UPS

Sir please make a video on High speed earth in GIS

[@avijitdas4706]

Sir, please tale me what is trap charger, how it's come to both link,

[@rupaliranaleaderdevotee]

3:00 TRV has several times higher frequency than normal system voltage

[@bullohsemak8959]

Tq sir love this video

[@GauravJ]

Thank you 😊 do share and subscribe 😇

[@rupaliranaleaderdevotee]

It can cause reigniting and rearcing

[@DeepakKumar-um3my]

First view sir I always support you 🙏🙏 But I have a recommendation create one more channel with Hindi Language except technical terms ❤️❤️

[@PlayboyHZ]

No, continue to speak english to hit a wider audience.

[@rupaliranaleaderdevotee]

Race is there conducting state and insulating state

[@rupaliranaleaderdevotee]

Fast changing voltages are there

[@rupaliranaleaderdevotee]

Interrupter should be able to handle these fast changing voltages
