- Describe construction and characteristic of CVT. Explain the behavior of saturated magnetic core in detail with change of supply voltage magnitude. It explain how decrease of input voltage produce boost action from L-C circuit and increase of voltage produce voltage division action from the same circuit. Fast, step less, magical correction of voltage takes place by change of magnetic properties of saturate core, without any relay action.
Better notes, good explanation makes it the best for the topic. Very good for every student. link for notes

🌷बहुत ही सराहनीय कार्य कर रहे हैं आप श्री मान जी 🌷
बहुत बहुत धन्यवाद . आपकी सराहना योग्य काम और कर पाए इसी की चाहत है
Great knowledge sir.
So nice of you. Time to thanks my teachers, as it is their knowledge which is here.
Very nice sirji....👌
Good explanation....👍
Thanks and welcome
अत्यंत उपयोगी🙏🙏
Thanks
Wonderful explaination
Thank you
Bahut Behtrin samjhaya Aapne bhai
thanks. watch other work too
does the capacitor feed the primary side of the transformer also if we have a load for example ? or just the secondary side ?
no. It can feed only reactive power.
Cvt aur ups ko kisi machine ke saath back to bak use karna sahi hai ya nahi pl bataye
All good quality UPS has CVT in output stage for voltage regulation but voltage regulation produces error, if frequency of UPS or inverter changes.
🙏🙏Please sir
ok
Please explain servo voltage stabilizer
Check our video on servo stabilizer.
Here is the link: th-cam.com/video/wMNIvTFLnMw/w-d-xo.html
Sir, Can possible welding machine from c.v.transformer ?
welding machine doesn't required stable voltage or stablizer for routine functions. It is in general heavy load and may damage CVT by high current drawn and in switching over voltages.
Sir how much the air gap in cvt transformer core ?
(0.1 mm or 0.2 mm)
for saturable part of core, there is no air gap. in other linear part there may be gap of size depends upon design.
सर CVT मे मेन्स input voltage 235v होने पर output 213v आ रहा और जब जनरेटर input voltage 245v होने पर 224v आ रहा है जबकि नेमप्लेट पर 220v काॅंस्टंट लिखा गया है इसका करता कारण है
generator may have frequency other than mains
Kia is type ka transformer battery charger k liay istemal kr saktay hain?
this is not transformer it is stabilizer only
How much amp taken by 3KVA CVT in no load condition
around 6A, 40% of full load
Capacitor voltage transformer and constant voltage transformer both are different or same . Plz solve problem .
they are two names of one. It is also ferro resonant stabilizer
How to calculate the proper value of the Linear Inductor?
kindly confirm the concern of your question for proper reply
we want to manufacture cvt . We require consultant for designing and manufacuring cvt from 50 va to 10 kva 1 phase
Please wait. We will do something. send your detail on email
if we need CVT with size = 250 VA, but we choose 500 VA instead .. is there any problem?
yes voltage regulation may not be maintained.
@@ShreeDeviClasses
Can you please explain more by - for example- giving formula for the sizing with the regulation. Or explain by words
magnetic core has non linear characteristic. In linear elements we have proportional relations and mathematical circuit models but the same is not possible with non linear components. Here in underloaded conditions core remain saturated and give under voltage output. Check over voltage operation of CVT in video, it may clear your doubt.
could you olease send me this video in english or pdf ?
