Considerations when building a HV RF transformer?
- I should think your primary concern should be the safety angle. How will the transformer be isolated from the public?s
why doesn't the emf induced in the primary of a transformer does not cancel out with the supply voltage?
- Leaving aside the double negative, the problem is your use of cancel - what do you expect - that it will go back to the generator and kill it? The transformer produces an output voltage which tries to do work against a resistance or inductance - the work it does produces a back EMF which the supply voltage works against so the generator has to do work. If there were no EMF in the primary, it would behave like a short circuit and blow the circuit - which is does in a small scale in the starting surge that you have to allow for when turning on equipment.s
50 What is the actual power of the transformer? Is 3 phase 50 or 3 together 50
- 50KVA transformer is the apparent power, the actual power close to 50KW.3 phase power a total of 50KW.s
Will the 250KVA, 500KVA, 630KVA Van transformer size,
- Box transformer inside the configuration is not the same, the size will be different, which factory production size is not the sames
Does anyone know what the movie was without a name on the transformer previews?
- this is so funny because i was going to ask the same question on here. hahahahaha.s
What if I put a rectifier before the transformer?
- You are asking some strange questions. You do not have a very good understanding of transformers. A transformer ONLY works with AC. This is why Tesla argued for AC being supplied to houses. With a simple transformer, the voltage could be increased for less loss on transmission lines and then with a step down transformer, the AC could be brought into homes. Edison, on the other hand, loved DC and wanted all houses to be supplied with DC. Edison, in an attempt to prove Tesla wrong, invented the electric chair to show how dangerous the larger voltages would be. Edison even electrocuted animals in his electric chair to demonstrate the effects of higher voltages. Fortunately, Tesla won the argument, or we would not be able to transmit electricity over high power lines from generators to homes. Now, a rectifier in the strict sense, does not change AC to DC (with ripple) but simply reflects the negative wave to make it positive. Thus adding a DC component and doubling the frequency. The DC component will simply pass through the transformer (no heating) and the higher frequency will work just great with the transformer. In fact, you can make smaller transformers by using higher frequencies. This was a technique that Sony used many years ago to make great amplifiers and Fisher and Paykel use to make better appliances. (Other companies might also, but I am not aware of them.) So, your transformer will only see an input of 60 V AC and step that down to 12 V. Thus, you will not have the 24 v you need. Why don't you get a better bridge??s
House near a polyphase transformer?
- Poly-phase transformers which are merely 3-phase transformers don't really cause anymore interference than any other transformer. If the thing was up against your wall, then maybe it would mess with radio or cell phone communications, but really your main interference concerns would be if you were near high voltage transmission lines. Why not ask the previous owners or neighbors in the area if this transformer has interfered with their electronics.I doubt it.s
Can the transformer oil be used as a lubricant?
- Can not.
Because the main role of transformer oil insulation is not lubrication.
Its water absorption is strong.s
