Frequently Asked Questions

Can I use a transformer to change three-phase to single-phase?

Frequently Asked Questions - Jefferson Electric
It is not possible for a transformer to present a balanced load to the supply and deliver a single-phase output. Changing three-phase to two-phase, and vice-versa, can be done using special circuitry with standard dual-wound transformers.

Can I connect a single-phase transformer to a three-phase source?

Frequently Asked Questions - Jefferson Electric
Yes, and the transformer output will be single-phase. Simply connect any two wires from a 3- or 4-wire source to the transformer's two primary leads. Three single-phase transformers can be used for three-phase applications. They can be used in delta-connected primary and wye or delta-connected secondary. To avoid an unstable secondary voltage, NEVER connect wye primary to delta secondary.

Can a single phase transformer be used in a three-phase operation?

Micron Transformers | Tech Support & Resources | FAQs: L...
Connect the primary leads to any two wires of the three phase source to obtain a single phase output using a single transformer. Bank three single phase transformers to be connected in either a delta-delta or delta-wye configuration for a three phase output. The equivalent three phase capacity when properly connected is three times the nameplate rating of each individual single phase transformer.

What is a phase change ?

Self-Organizing Systems FAQ for Usenet newsgroup comp.theory...
A point at which the appearance of the system changes suddenly. In physical systems the change from solid to liquid is a good example. Non-physical systems can also exhibit phase changes, although this use of the term is more controversial. Generally we regard our system as existing in one of three phases. If the system exhibits a fixed behaviour then we regard it as being in the solid realm, if the behaviour is chaotic then we assign it to the gas realm.

Can I use single phase power to run my three phase spindle motor?

Ajax CNC -- Frequently Asked Questions
Yes, and without the expense and difficulty of a phase converter! Simply use an Inverter/VFD that accepts single phase power ( most newer models do) and let it create its own three-phase, which is much more stable than ANY phase converter can produce. Just make sure to buy an Inverter rated for one size larger spindle motor ( ex. 2HP Spindle, 3HP Inverter). Go to www.ajaxcnc.com/partsources.htm to see where we buy ours!

What is a transformer?

Dapper: Frequently Asked Questions
A transformer is a tool that takes the output of a Dapp and converts it to another format. Current transformers include: RSS, email, HTML, Google Maps, and more. To transform a Dapp, find or create a Dapp and then click the 'more uses' button to see the available set of transformers.

What is the significance of Phase shifting transformer / Phase shift angle?

Untitled Document
Phase shifting transformer is used in certain systems to push more power in a specific line by introducing angle difference . The phase shift angle in the element data corresponds to the shift given to boost the power flow. Phase angle in the library is the phase shift introduced due to vector connection i.e. 1'O clock position or 11' O clock position etc. The Tie line refers to those lines connecting one utility to other or those lines, which island the system, when kept open.

In which phase do absorbance values steadily change and why?

Highlights and FAQ's
In the lag phase, the absorbance of the product is unstable; in the reacting phase, the absorbance steadily changes provided the temperature and pH are controlled. If there is more reactant, that reagent can react with, the third phase - reagent depletion - occurs. In this phase, the absorbance values remain the same.

Will the accession number change when the Phase changes?

No. The accession number you receive when you first submit an HTG record remains with that record throughout its existence, that is, through its various phases and any updates of its sequence and/or annotations.

What if I only use single-use instruments?

Cosmetology Frequently Asked Questions
If a barber or cosmetology shop, salon, or school only utilizes single-use manicure/pedicure instruments, then the sterilization requirement would not apply.

How do I know if I have 240 or 208 volts and single or three phase?

FREQUENTLY ASKED QUESTIONS FOR L&L CERAMIC KILNS
Most household electrical current is 240 volts, single phase. Industrial or commercial can be anything. If you aren't sure ask your electrical utility company or an electrician. It is important to know because it can be expensive to convert a kiln form one voltage to another. See complete technical information on voltage for more information. Not normally. You still use the same amount of KW hours regardless of the phase of the power.

Can I get a single phase fire pump?

Steven Brown Associates Sales and Service of fire pumps and ...
Yes, provided that the motor HP does not exceed 15, and the job site voltage is 230 volt. The motors on these units are not currently Listed for fire protection, but the control panels on the fire pumps are. Cost increases are moderate.

Can I build my own transformer?

Dapper: Frequently Asked Questions
Yes. Transformers are tools which transform the raw XML produced by Dapper to various useful formats. Soon, we will release the code of the existing transformers and an API that will allow you to build new transformers and add them to the current existing list.

Do any of your Monopoints / Multipoints allow the use of a remote transformer?

Frequently Asked Low Voltage Monorail, Mono/Multi -Point and...
Our QMP-M1RN-TR and QMP-MI Monopoints allow the use of a remote low voltage transformer. The Multipoints all have integral electronic low voltage transformers.

Can I use my several appliances at once with voltage transformer ?

Voltage Converters, Power Converter, Inverters, Adapter Plug...
Yes, As long as total wattage of all your appliances do not exceed than the wattage capacity of a voltage transformer. Also consider only 80% wattage capacity of voltage converter than wattage rating of your appliance(s) to avoid damage caused by power fluctuation. Yes, since there is no worldwide standard for the plug configuration, plug shapes and plug holes (electrical outlets) differ from country to country.

Can I use several appliances on the same transformer?

DC AC Power Inverters - F.A.Q's
Yes as long as you don't exceed the Wattage capacity of the voltage converter. A "surge protector" is required. You can find them on this web-site as well. Example: If you want to operate 2 appliances on one transformer. One of them consumes 300 watts and the other 130 watts then you would need a VC-500 (500 watts capacity) or higher. VC model transformers come with a European-to-American plug adapter GS29 (universal input and output of 2 flat pin grounded).

How does the use of an electronic transformer differ from the use of a magnetic transformer?

FAQ
The output of an electronic transformer, unless it is a DC transformer, is high frequency. This has the consequence that there is substantial voltage drop if the wires carrying the current are long or far apart. Always obey the following rules to avoid a voltage drop. Use thick wires on the secondary/output side. The thicker the wire the less drop voltage you will experience. The shorter the distance between transformer and lamp the less drop voltage you will experience.
