- 11KV STELMEC Breaker in Vacuum Interrupter working problem so change VI and normal checking, Testing and Maintenance practical vidio.
VI Make:- CGL Type:- WL-33379M3+
In a low voltage circuit breaker, using air or arc chutes is sufficient to extinguish an arc. In the medium voltage range (1000 volts to 38 kV), the main technology used to extinguish an arc is the vacuum interrupter. Vacuum interrupter technology is used for repetitive switching, motor inrush current interruption, fault protection, overcurrent, and short-circuit protection.
The vacuum interrupter is a pair of separable contacts (primary contacts), enclosed in a vacuum-tight envelope. The envelope itself is a ceramic material, with a metal end plate brazed to each end. The metal plates seal the ends and provide support for the parts inside.
Of the two contacts (electrodes) inside, one is fixed. The other is movable, through a bellows-type connection. Various shields inside the envelope provide different types of protection to interrupter parts.
• Circuit breakers - Used in circuit breakers in the most demanding electrical circuit protection applications to minimize damage caused by electrical overloads or short circuits.
• Load break switches - Used in load break switches to connect and disconnect electrical load currents providing limited load switch capacity.
• Reclosers - Used in reclosers to automatically open and close distribution circuits in response to transient overload and fault conditions.
• Contactors - Used in contactors in demanding applications that require a high number of operations switching a power circuit in electric motors, lighting, heating devices, and capacitor banks.
Since the arc is contained within the interrupter, switchgear using vacuum interrupters are very compact compared with switchgear using air, SF6 or oil as arc-suppression medium. Vacuum interrupters can be used for circuit-breakers and load switches. Circuit-breaker vacuum interrupters are primarily used in the power sector in substation and power-generation facilities, and load-switching vacuum interrupters are used for power-grid end users.

Very nice knowledgeable video vcb interrupted test and change procedure
Sir aapka video achha rhata hai fir bhi aap bahoot kam video banate hia sir vcb assembly ka banaiye na
Keep it up
Thanks for video
Thanks...
Vah Dilip bhai...go ahead chalu rakho nava nava video....
Thanks
th-cam.com/video/0LfWjt81mg0/w-d-xo.html
Good sir
Vedio is very good but sir ji details aap batate hai o adhura hai aap jo bhi explain karte hai kab ,kyon kaise larana hai kitana voltage aply karna hai sab kuch bataye thoda aur behtar hoga kyonki apko knowledge bhut hai
Nice vidoes🙏🙏
Thanks
Clear info
Well done Dilip bhai
Thanks bhai...
Supper sir , I subscribed your channel, great information
Thanks
🙏🙏🙏🙏
Good explained
Thanks
Good knowledge
Thanks
Sir ye test kit ka naam kya hai? Can you please share?
Dear sir kindly JRP 012 12A relay setting ke baare mein full detail mein btaana..
Nice sir
Thanks and welcome
Sir do video on sf6 circuit breaker
Sir vaccum check kar rhe hote hain to usme kitna KV inject hota hai
Jo hmaare yhan pe hain usme shows nahi karta ki kitna KV inject ho rha hai
Vese iska koi formula hai ki itne pe hi hoga sir ?
Feeder trip hone p incomer hotter nhi bjta please btaye
6.6kv areva vcb ka vacuum interupter kaise change karte hai
Incomer vcb m hotter circuit btaye I am a sub station operater in haryana
Sir jis instrument se apne vi ko check kiya tha uska kya name hai
High voltage test kit
@@VadiyatarDilip sir kha melegi ye
Aapka contact no sir
Ye kitne KV rating ka breaker tha...jispe aapne 16kv pe test kiya?
11kv ka interruptor hai jiska rating 12kv ka hota hai
Sir intruptter me heating ka kya reason ho skta hai.. Please reply
Interrupter me jab switching arc ko clinch karne ka medium rahta nahi jese vacuum chala jaye to aapka HT switch interrupter me circuit break nahi hoti aur switch contect open hote he to aese me arc chalti raheti he aur interrupter over heated hota hai
Hi sir
information is incomplete, if you make video to guide someone make full proper video, by the way setting is main part that you didn’t tell
Ok
Dilip bhai 66kv abb bekar no vidiyo banavo ne
Thaku sir
