Q:Transformer input power how to ask?
Transformer calculates power factor If the capacity of the power transformer is denoted by S, the output active power is expressed by P, then the power factor cosa = P / S.
Q:whats transformer kva rating I need?
Your connected load is about 250 kW plus about another 700 kW (from the motors when taking into account efficency and Power Factor). So the total connected load is just under 1000 kw. This 1000 kw is about 1 MegaWatt ( MW). A MegaWatt is 1000 kW You want to oversize your transformer, to account for added load at a later time as well. If I was ordering the transformer, I would be looking at one to cover at least a 1.5 MW. This would be roughly a 1,500 kVA transformer. You could order one slightly smaller, and add cooling fans which come on at max loads to cool down the transformer and increase its kVA rating. Because you have a large motor load, you will likely need the full 1500 kVA unit, because of the Power Factor issues with motor loads. BTW --- there may be a 1 year lead time on ordering a transformer that size.
Q:How do you choose the public transformer capacity?
In the actual choice, should adhere to the "small capacity, dense point" principle Distribution transformer location should be located in the load center, and the power supply radius of not more than 0.5 km. Distribution transformer load rate between 0.5 to 0.6 the highest efficiency, At this time the capacity of the transformer is called the economic capacity. But if the load is relatively stable, then the continuous production of the situation can be selected according to economic capacity transformer capacity.
Q:Transformer core
The core part of the transformer is composed of (primary coil) and (secondary coil), generally divided into two types of step-up transformer and step-down transformer. (In fact, there is not a step up and not buck the isolation transformer) Did not hear the transformer "what son".
Q:Flyback Transformer Clarification & help?
You might find whether your transformer is broken with an ohmmeter between the ultor cap and a pin by trying each with the meter set to a high ohms range, with (I think) the black meter lead connected to the ultor. If you don't see a result 1st. time around, try swapping the meter leads. If you get a result, try the 24V test there. If you don't, and using his method also fails, I think you have a dud. So far as the 9V test, I think that has a fatal flaw. A digital multimeter, or usually also an analogue one, cannot respond fast enough to a single pulse. A digital meter only samples at a certain rate, and if the voltage does not align with the sampling, you see nothing. Even if it does, I think you would only see an instantaneous reading before next sample sees nothing. Apart from that, the voltage spike will be well over 200V! The object is to sort out input direction in the primary. I would suggest you sort out the primary connections, and build the circuit. I have not looked at it, but I think if you fire it up, you will either have + HV coming from the ultor cap, or nothing. If nothing, reverse the primary. DON'T TEST IT WITH YOUR FINGERS!!!
Q:Question on transformers?
Since there is no evidence to indicate any inefficiency of this transformer, you have to assume that it is 100% efficient, with input power equaling output power. Input power Vin * Iin Output power Vout*Iout Equate: Vin*Iin Vout*Iout Solve for Iin, our unknown: Iin Iout * Vout/Vin Data: Vout 110 V Vin 230 V Iout 0.15 A Result: Iin 0.072 As for the ratio of loops, the number of turns in each coil is proportional to the voltage across each coil. Thus, the turns ratio equals the voltage ratio of 110/230 0.478. That is to say, there are 2.1 turns in the primary coil for every individual turn there is in the secondary coil. The primary coil is the coil plugged in to the line voltage of 230 V. The secondary coil is the coil in to which the load plugs in, at load voltage of 110 V.
Q:What will happen at primary side of transformer?
the transformer converts Watts if it is rated at 12V 3A it means 36 Watts if you load-it more than that it will overheat and eventually burn the primary current is proportional to the secondary current however with an overload of 5 A as oppose to a load of 3 A it may last for several hours before becoming too hot the answer is yes you can run your load for a while provided that you monitor the temperature and watch the situation however do not load over 3 times the rating (8~9A) for any length of time more than 1 second A
Q:about TRANSFORMERS!!!?
27. (a) More than that of transformer B 28. (a) Pulsating magnetic flux 29. I do not think there is such a limitation on ONAN transformers. 30. (a) 100
Q:Can dry transformers and distribution cabinets be placed in the same room?
Dry transformers and power distribution cabinets can be placed in the same room. Oil-immersed insulation with insulating oil, dry type with resin insulation, dry-type safety is better than oil-immersed transformers. In the event of a fire or explosion, oil-immersed insulating oil may increase the risk of accidents, so need to be set separately, and the transformer base should have oil leakage design. And dry type change will not have such a danger, it can and power distribution cabinet set in a room, while dry-type transformers and distribution cabinets in the same room easy to overlap, busbar and cable consumption on the reduction, operation and maintenance More convenient, articulated ground and check the power outage when the glance.
Q:Proteus transformer how to adjust the parameters, the 220V into 14V output.
The above two parameters can also be extended or reduced by the ratio. Other parameters can be considered, as shown below.
