Emerson brand, is the best power transformer (one person's opinion).
..What do you mean by "Best"? "Best" can be defined as:
1. Cheapest
2. Smallest
3. Most efficient
4. Quietest
5. Most resistant to through fault current, overheating, over voltages, etc.
or a mixture of the above (and other reasons that I haven't mentioned).

Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What does LT stand for in power transformer?
Transformer Inductance?
What is the main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
Can a a electric substation in a city use transformers to increase the power output?
No! A transformer changes voltage levels, not power levels. In fact, the output power of a transformer is actually a little lower than its input power, due to the efficiency of a transformer.
Why the power factor of load is not fixed on the transformer?
Because the transformer designer does not know the power factors of the different loads that might be connected to it. The way round this probem is to specify the voltage and the maximum current that the transformer can supply, then multply them together and print the VA, kVA or MVA rating on the transformer. Then it's up to the user to comply with this rating to avoid damaging the transformer.
What is meant by the term ideal transformer?
ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer
Is transformer an amplifier?

What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
What will happen you f the rated power of transformer is changed?
You cannot 'change' the 'rated power' of a transformer except by changing the transformer for another one. You can, though, operate the transformer below its rated power or, for short periods of time, operate the transformer aboveits rated power.

What type of grounding is implemented near power transformer in generating plant?
Kobe is the best basketball player
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
What does LT stand for in power transformer?
Transformer Inductance?
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
Why transformer power factor taken unity?
It isn't! A transformer operating at no load has a very low power factor.
When was Adams Power Plant Transformer House created?
Adams Power Plant Transformer House was created in 1895.
Why the power factor of a transformer is poor at no load?
The inductance of the transformer is much higher than the resistance of the transformer, resulting in very low real power losses (in watts), but some reactive power (vars).
