Cooling will impact load losses (Since the resistance of copper will increase as it's temperature increases); Core losses are a characteristic of the transformer, so there is nothing you can do about them after it has been made. Insuring you aren't overexciting the transformer (overvoltaging) may help if you periodically have high voltages.

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.
How to calculate transformer core loss and iron loss?
there are several losses in a transformer that prevent it from attaining 100% efficiency. One is core loss, which can be divided into Hysteresis losses, Eddy currents and Magnetostriction loses. see for more details http://en.wikipedia.org/wiki/Transformer#Energy_losses
What will happen to the efficiency of a transformer if the iron core is removed?
its efficiency will decresed.
How does eddy current loss effect a transformer?
Eddy currents act to increase the temperature of a transformer's core above ambient temperature, resulting in a loss of energy through heat transfer -thus reducing its efficiency.
What is the percent efficiency of an open delta connected transformer?
67%
Can you increase the efficiency of transformer by increasing the cooling of transformer?
nope
What is the efficiency of a transformer?
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
When is the efficiency maximum in a transformer?
the efficiency is maximum in a transformer when no load loss is equal to load loss.

What is maximum efficiency condition in distribution transformer?
The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss
How does eddy current loss effect a transformer?
Eddy currents act to increase the temperature of a transformer's core above ambient temperature, resulting in a loss of energy through heat transfer -thus reducing its efficiency.
What is the percentage load at which maximum efficiency occurs for the single phase transformer?
That is the maximum efficiency occurs when the copper losses are equal to the core losses of the transformer.
What is transformer coupling in power amplifiers?
in certain power amplifiers(cls A,cls C etc.) the output sometimes not directly taken. rather it's coupled with transformer and then transferred power is applied to the load..this is transformer coupling..... there are two main reasons to do so 1. in order to increase the efficiency.(exmpl: efficiency of class A power amplifier increase by almost 25%) 2.in order to get smooth i.e; distortion less output.. by Jishnu Mukherjee (Kolkata,India)
What will happen if iron losses and copper losses are equal for any transformer?
The transformer will have the maximum efficiency.
Why the efficiency of a power transformer increases with a decrease in Load at constant PF?
Maximum efficiency of a power transformer occurs when copper loss equals to iron losses. Decrease in current does not result in increase in efficiency unless the copper loss was more than iron loss and the decreased current made the copper loss is reduced and became equal to iron loss at some point.
