efisiensi trafo

Perhitungan daya pada rangkaian AC (arus bolak balik)

berikut ini link materi terkait utk merefresh kembali teori rangkaian RLC :
web.ipb.ac.id/~tepfteta/elearning/media/Energi%20dan%20Listrik%20Pertanian/MATERI%20WEB%20ELP/Bab%20VIII%20RANGKAIAN%20RLC/indexRLC.htm


Daya riil yg diserap oleh rangkaian adalah : P = v * i * pf
dimana, pf (power factor atau faktor daya) adalah = cosinus(phi)
dimana, phi = beda fasa antara tegangan dg arus

1. pada rangkaian resistif murni
   tidak ada beda fasa, phi = 0, maka cos(phi) = cos(0) = 1
   P = v * i * 1 = v * i


2. pada rangkaian induktif murni
   beda fasa = 90 (arus tertinggal 90 dari tegangan)
   maka cos(90) = 0
   P = v * i * 0 = 0

   arus ada, tegangan ada, tapi P = 0
   P = 0, artinya : daya sesaat yang dihasilkan adalah bernilai positif dan negatif
secara bergantian.  Daya yang bernilai negatif menunjukkan bahwa daya dilepas
kembali oleh induktor ke rangkaian.  Karena perbedaan positip dan negatip
besarnya sama dan dalam waktu yang sama maka resultannya adalah nol.  Oleh
karena itu kalau sumbernya adalah generator maka daya akan dikembalikan ke
sumber sehingga tidak perlu energi mekanis untuk menggerakkan generator dan
induktor tidak menjadi panas


3. Lilitan pada trafo, ketika tanpa beban (No Load)
   tentu saja pada alam nyata, tidak ada induktor yg bersifat induktif murni,
   karena tiap kawat tembaga ada resistansinya.
   sehingga beda fasa tidak bulat 90, misalnya 86


4. Trafo, ketika dibebani (ON Load : pd lilitan sekunder dihubungkan beban)
   pada lilitan sekunder mengalir arus :
   - maka akan timbul flux magnet yg berlawanan dg flux dari lilitan primer
   - maka ini akan membuat induktansi pada lilitan primer menurun
   - shg reaktansi (XL) pd lilitan primer menurun
   - shg Z (impedansi) lilitan primer menurun
   - shg i yg mengalir ke primer membesar --> trafo terasa lbh panas.

   pada kondisi ini, beda fasa semakin berkurang,
   misalnya dari No load 86, mjd 75 pada ON Load


Thane C Heins, mendesain suatu bentuk trafo yg:
- pada kondisi ON Load, beda fasa nya tidak berubah (atau sedikit sekali)
- shg ketika ON Load atau No Load, beda fasa tetap di dekat 90
- di dekat 90 artinya : faktor daya dekat cos(90) = 0

Terima kasih sharingnya.

Saya melihat ada beberapa kendala mengimplementasikan teknologi ini:
1. kebanyakan alat free energy butuh listrik DC.
2. Alat free energy yang butuh AC cara bekerjanya biasanya pakai kumparan yang mungkin tidak kompatible dengan teknologi ini, contoh kapanadze.
3. untuk mengubah voltase di teknologi charge batre biasanya inputnya DC dan outputnya DC. untuk radiant charger sudah punya kemampunya menyesuaikan voltase output dengan beban karena secara prinsip sama dengan teknologi buck boost.
4. untuk mengubah voltase di teknologi penangkap skalar biasanya butuh yang bisa bekerja dengan frekuensi tinggi sehingga biasanya malah dilakukan tanpa core (air core / inti udara).

Kekurangan ini membuat implementasi self generation menjadi rumit, sehingga implementasi sepertinya lebih mudah bila digabungkan di bagian motor generator.

Open letter to Thane

Hi everybody!



It's the second time I write to Thane without answer while I think my question is valid (I can very conceive he's much busy), so I make a copy of here as an "open letter" that you may comment



"Hi Thane and Very Well Done for all your major breakthrough.



I'm electrician myself, have my own business in France, work on the subject of free energy, especially on a device that look much to your Bi-Toroide but without core and not with the primary out inside, working by atomic resonating and Tesla principals.



I've seen many of your videos recently and something bother me:



You speak about "Watt" at the input, and you state: 0V*0.125=0W because of the power factor, but in many country the grid makes pay for V*A, what we call here, in France "puissance absorbée" ("absorbed power"), no Watt, means with reactive power["VAR" or "RAV"?], or like in France, we are not allowed to make installations with a power factor too much important (very small indeed) if not compensated by sets of capacitors. (A bit like with fluo-bulbs having no capacitor inside that cost near 50% energy than it says on it)



So, as I'm interested both by your own ideas and realizations to distribute ans install them in France, could you precise me the COP you get in your tow system, static and rotative, but with this formulas: POWER DELIVERED by the generator with a significant load / POWER ABSORBED at this input, with as formula for "apparent power":



(APPARENT POWER [Watts]^2 * REACTIVE POWER [VAR]^2)^(1/2)



Cause I remember you again: even if you say you measure "0V" at the input, when you read "0.125A" same time(like in your demo for the BiTT) you do pay to the grid, aren't me true? and any way, how could be "0V" if plugged and switched-on?!! :/



Cheers, Khwartz"

Dr. Grbovic

Dear Gentlemen,

As a professional with more than 15 years of experience in academia and industry, I have to say that all this story about Bi Toroidal Transformer and efficiency above 100% (even above 1000%!!!) is absolutely nonsense. All of us very well know that efficiency cannot be above 100%. That is the fact. All the tests and measurements done by third party (Dr. Fusina from Defense Research Lab) are also completely wrong. I asked Thane to send me one transformer to do test and measure real efficiency, but it seems, he does not like that idea.

What he made is just a transformer with very high leakage inductance, nothing else. That is reason why the power factor is almost zero. And, to measure the input power when the power factor is also zero is very difficult. Especially difficulty using primitive method and equipment he uses. The input power must be measured using completely different methodology. Then, you will see, the efficiency is not above 100%, not at all. If I have a chance to have transformer to test it, I will post the real efficiency data.

Bottom line is without the grid it is nothing, try it with an inverter run from a

battery. The inverter will keep pulling current I think. Is it actually plugged

into the wall or is it using some other supply because it sounds like it's

working in the Khz range it's ringing.



This is similar to Thanes setup in that without the grid it is nothing I think. It's

fairly easy to load up a transformer with flux using power, to the point of flux

leaking then drain some of the flux to light a load and reduce current by doing

it. It depends on where the current is measured and the supply train back to

the source, if like thane he is using a variac and driving another transformer

from the wall then using that to drive those (device) transformers then all sorts of

funny things can be shown because the power from the wall to the first

transformer can be much more than the power from the transformer to the

device. But the current is measured between the Transformer and the

device not from the wall directly.



In this video here starting at 2:30 minutes the effect made itself known to me. It

shows the effect quite clearly in my opinion. At first during the video I didn't

realize what happened. My input goes from 1 amp at 12.5 volts with no load

to 0.3 amps at 12.5 volts with the load added. That's a drop of 8.75 watts

when the load was added. But it's nothing special, it's just what can happen

sometimes, it's backwards, and it's not a good thing in my opinion, it restricts

the possible loads that can be run. Of course.

In this video here at 9:27 minutes I adjust the current to almost zero. The

load is still powered.

Test -7.wmv - YouTube



These video's of mine are rough and ready but I was not trying to impress

anyone or make any claims. Take them for what they are.



This effect is very limited in that when the transformer is setup at idle it uses

substantial input power then when the load is added it only has access to

that much power, that's it when the input gets near zero that is the end of

the effect and it is not OU. Not in my opinion, best way to find out is power it from an inverter and a 12 volt battery.



Cheers
