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 you increase the efficiency of transformer by increasing the cooling of transformer?

nope


What is the percentage load at which maximum efficiency occurs for the single phase transformer?

For a single-phase transformer, maximum efficiency typically occurs at around 50-70% of the rated load. Operating the transformer at this load range minimizes losses and improves efficiency. Going below or above this range can decrease efficiency and increase losses in the transformer.


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 happens when frequency is increased of transformer?

When the frequency of a transformer is increased, the core losses of the transformer increase due to increased eddy current losses and hysteresis losses. This results in a rise in temperature of the transformer. Additionally, higher frequency can affect the impedance of the transformer and alter the voltage regulation and efficiency.


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 maximum efficiency condition in distribution transformer?

The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss


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 is the efficiency of a transformer that has an input of 600 VA and an output to a load of 580 VA?

The efficiency of a transformer is calculated by dividing the output power by the input power, then multiplying by 100 to get a percentage. In this case, the efficiency would be: (580 VA / 600 VA) * 100 = 96.67%. This means the transformer is operating at around 96.67% efficiency.
