Apart from transformers what other instrument can you use to step down voltage?

resistors - and they have to be physically large enought to dissipate the heat of the voltage x current you will drop out.

What is ferro-resonance effects?
The effects of ferro-resonance are the ungrounded primary transformers, higher distribution in the voltage systems. Other effects are the lightly loaded transformers.
What is rm6 by schneider?
A piece of Medium Voltage switchgear, commonly referred to as a "Ring Main Unit" (RMU), It reticulates power to other MV pieces of equipment such as transformers.
Why ac the more prevaeant form of distribution?
High voltages are necessary for transmission/distribution of electrical energy because, for a given load, the higher the voltage, the lower the resulting load current -which means that voltage drops along the lines can be maintained realistically low (amongst other advantages). A.C. is, therefore, more prevalent because its voltage levels can be changed easily and very efficiently using transformers. Transformers will not work with d.c.
What is bus potential transformer in electrical?
Potential transformers are instrument transformers. They have a large number of primary turns and a few number of secondary turns. It is used to control the large value of voltage.WORKING:The potential transformer works along the same principle of other transformers. It converts voltages from high to low. It will take the thousands of volts behind power transmission systems and step the voltage down to something that meters can handle. These transformers work for single and three phase systems, and are attached at a point where it is convenient to measure the voltage.
Can a Dy11 vector group transformer be connected to a Yd1 vector group transformer source?
In series, yes. In parallel, nope! Putting a Yd1 transformer in series with a Dy11 transformer would result in the output of the Dy11 transformer being identical to the input of the Yd1 transformer with the exception of the voltage magnitude - this will change depending on the winding ratio's on both transformers. But, in regards to other properties of the voltage, the phases will in be in phase, with the voltage in-between the two transformers lagging by 30 degrees.
What are the two types of transformers?
The two general categories of transformer, based on their construction, are (a) mutual transformers and (b) autotransformers.Mutual transformers have two coils, or 'windings', termed the primary (input side) and the secondary (output side), which are electrically isolated from each other, being linked with a magnetic field.Autotransformers have a single, shared, winding and so, do not provide isolation between the primary and secondary sides.Mutual transformers can be further classified, according to their function: e.g. power transformers, distribution transformers, isolation transformers, instrument transformers, matching transformers, etc.
Dangers of living near electricity voltage transformers towers?
Living near electricity voltage transformers towers, increases your risk of cancer and other health problems. Numerous studies done worldwide confirm this fact.
What is ferro-resonance effects?
The effects of ferro-resonance are the ungrounded primary transformers, higher distribution in the voltage systems. Other effects are the lightly loaded transformers.
How do wall transformers work?
Just like any other transformer - voltage is applied to one winding, which induces a magnetic field in the transformer core, which induces a voltage on the other winding.
Can you put transformers in series to double your voltage?
You can if done carefully. The neutral of one transformer must be set up to be at the positive voltage of the other transformer. This might require an intermediate step transformer that is center tapped (so three instead of 2 transformers).
Is transfomer output voltage designed to full load?
Transformers are designed to run at specific voltage levels, and they are designed to handle a maximum load (known as "full load"); this load is usually based on the amount of current that can be pushed through the transformer without overheating, so if 1/2 voltage is applied, full load would be 1/2 of normal. Some "complicated" transformers may have other limitations (dual voltage transformers may have two different full loads specified, and they may not be directly proportional relative to voltage).
How do electricity suppliers get the electricity?
Generators supply electricity to transformers. Then the transformers increase the voltage to reduce voltage drop as the electricity travels over long distances. When the power gets to its destination, other transformers reduce the voltage back down to a useable level.
What is rm6 by schneider?
A piece of Medium Voltage switchgear, commonly referred to as a "Ring Main Unit" (RMU), It reticulates power to other MV pieces of equipment such as transformers.
The name of transforming robot movies apart from transformers and gobots?
well, there's a lot of other generations of the TFs. check out sparkholder.webs.com for some good links!

Why do low voltage lighting transformers fail after a year?
Mostly they do not but transformer failure usually comes from overloading, in other words taking more current than the transformer was designed for.
Is there going to be any other transformers?
Yes There Will Be a Transformers Released In 2014 Called Transformers Rise Of Galvatron
