Function of no-load in transformer in a open-circuit?
To calculate the no load current from transformer & core loss is also calculated.
What is percentage of transformer loss at no load condition?
major component of power loss in a transformer is secondary resistance.when transformer is operated under no load,no current flows through the secondary.so under no load conditions transformer has just very small megnetic losses.
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
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 formula for gain in a power amplifier that has a step down transformer?
A: there is no formula the gain of the amp is just reduced by the transformer turn ratio minus efficiency or loss. the transformer is for isolation and impedance matching
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 are the signs of a fuel pump going out?
Hard starting Loss of power due to fuel starvation Noise coming from pump area
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 the method of checking density of transformer oil?
why mentioning loss angle 0.002 in transformer
A single-phase transformer when supplied from 220v50hz has eddy current loss of 50wif the transformer is connected to a voltage of 330v50hzthe eddy current loss will be?
112.5
Which loss in transformer varies significantly with load?
Copper loss varies with the load.
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
Why does Car have white smoke coming from head power loss and makes loud noise?
Bad head gasket? Cracked Head? CRacked block?
Function of no-load in transformer in a open-circuit?
To calculate the no load current from transformer & core loss is also calculated.
What is meant by the term transform?
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
How has noise induced hearing loss been reduced?
Laws that require protection from loud noise in the workplace have achieved substantial reduction in noise induced hearing loss.
What are affects of noise pollution?
loss of hearing (from excessive exposer to extreme noise pollution) and bags under the eyes (from loss of sleep :P)
