What else can I help you with?
How can you tell if a transformer is a set up or set down?
The same transformer can be both. It must be operated at the correct voltage on both windings.
What is a set down transformer?
A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.
How do i convert from 380 volts to 220 volts?
If these are the exact voltages that you need you will need an auto transformer to obtain these voltages. If these voltages are nominal voltages and are of a three phase four wire configuration, the 220 voltage can be obtained from the three phase legs to the neutral (ground) connection. The equation to use is 400/1.73 = 231 volts.
What is the minimum load require to put transformer?
A transformer requires a 75-kVA minimum load in order to be set.
What is the difference between Ohm and Ohm CT in impedance of an audio transformer?
The side of the transformer that has the ohm CT which translates into a winding on the transformer that has a center tap . This side of the transformer was likely attached directly to the audio output transistors set up in push pull configuration. This is what the center tap is for. This side of the transformer would have a higher impedance and is directly driven by the power supply to provide amplification The transformer also isolates the amplifier voltage from the other side which is of low impedance. This may be in the range of 8 to to 16 ohms which would be directly tied to a speaker.
What is the difference between a set down and a set up transformer?
Set down transformer are also referred to step down transformers. They are used in regulating the electrical voltage before it can be used to feed a house. While step up transformer are mainly found in the generation stations to improve the voltage generated by the turbine. Thanks.

What is the difference between step up and step down?
in transformers for instance a stepup transformer does exactly that, steps up the voltageAND/OR theamperage and a step down transformer reduces the same. if you have a machine that operates on say 120 volts alternating current single phase and your building or power supply in your buildingis set up for or delivers480 volts alternating current-three phase you will need a step down transformer to operate the machine.
What are the powers of the Train Transformer?
A model train set will need a transformer to power it. On most modern train sets the power of the transformer is usually between 8 and 18 volts and will differ by manufacturer.
Why is a set up transformer needed in a stereo or tv set?
A stereo or tv set needs a step-up transformer because a step-up transformer increases the voltage of an appliance and a stereo or and a tv set needs a high voltage.-------Semper Fidelis(ADC)----------

Is a transformer load inductive or capacitive?
A transformer is fundamentally a set of coils; therefore, a transformer is an inductive load. However, by "transformer load", you seem to mean "the load that is connected to a transformer". Whether that load is inductive or capacitive depends mostly on what is hooked up to the transformer.
What is the minimum load require to put transformer?
A transformer requires a 75-kVA minimum load in order to be set.
Can you use any ho transformer for a ho train set?
As long as the transformer is capable of 12 Volts DC output, you can use any transformer with HO scale equipment.
What is the use of bucholz relay in transformer?
A Buchholz relay is located in an inclined pipe between a tranformer's tank and its expansion tank. It has two purposes: (1) to set off an alarm in the event of a loss of oil or the formation of an excessive amount of gas bubbles (likely caused by minor arcing between the turns of a winding), and (2) to disconnect the transformer in the event of a continued loss of oil, or a catastrophic fault within the transformer.
How you using ref relay in transformer?
an REF relay (restricted earth fault) is used to provide ground fault protection for a transformer. Its' operation is limited by CTs starred towards the transformer (usually on the transformer bushings or in breakers used to isolate the transformer), so it will only operate for transformer related faults. Because of this, it can be set to operate very quickly.
