at high voltage side, current is low. hence the size of conductors is reduced or small.
At low voltage side, current is high. Hence the size of conductors is large.

What is high voltage side?
You are probably describing a transformer. The 'high voltage side' of a transformer is the winding with the greatest number of terms. It could be the primary or the secondary winding.
How is high voltage used for the electricity that is delivered to your homes from regional generating stations?
The electricity that is delivered to homes from the regional generating stations uses high voltage in its distribution. This is then transformed from the high voltage on the primary side of the transformer to a lower voltage on the secondary side of the transformer. The common household voltage throughout North America is 120/240 volts obtained from the secondary windings of the step down utility owned transformer.
How do you calculate input voltage of a transformer given both side high and low side impedances and also load with power factor?
The input voltage (primary) and output (secondary) of a transformer is determined by the manufacturer. Transformers are bought to accommodate the voltage that is needed on the primary side and to what voltage is needed on the secondary side.
Why were instrument of a transformer placed on a high voltage side in short circuit test?
I assume "tension" in this question should be replaced with "voltage". Short circuit tests are often performed from the lower voltage side of the transformer, since a lower voltage source is then required to perform the test. Often times the test lab may not have a source that can output a high enough voltage to perform from the high voltage winding.
What is the amp rating of 100va transformer?
The amp rating for a 100VA transformer will vary depending on the actual voltage of the transformer. Transformers have both a primary and a secondary voltage.
What is high voltage side?
You are probably describing a transformer. The 'high voltage side' of a transformer is the winding with the greatest number of terms. It could be the primary or the secondary winding.
Is transformer side interchangeable?
yes,we can change the transformer side in transmission line as use of high current or high voltage in output.
Where is the high side of transformer on open circuit test?
high voltage side call primary
Why open circuit test is done on the transformer with low voltage side shorted?
The supply is given on the high voltage side of transformer because the supply voltage required to circulate rated current through the transformer is usually very small So energy is saved.
What is meant by high and low voltage sides of transformers?
Transformers are use to step up and step down the voltage of electricity. In a step up transformer, the voltage coming out is higher than the voltage going in so the output is the high side and the input the low side. In a step down transformer, the output is the low side.
Why you are using on load tap changer in primay of transformer?
The primary windings are bigger In size and it will be more accurate to tap it than tapping the smaller size secondary windings. Answer A tap changer is installed on the high-voltage side of a transformer, regardless of whether that transformer is a step-up or a step-down type. So, it isn't necessarily installed on the primary side of the transformer. The reason for this is that the current on the high-voltage side of the transformer is lower than on the low-voltage side, and the make/break contacts can be smaller. Also there are more turn on the high-voltage side so a finer degree of adjustment can be achieved.
How is high voltage used for the electricity that is delivered to your homes from regional generating stations?
The electricity that is delivered to homes from the regional generating stations uses high voltage in its distribution. This is then transformed from the high voltage on the primary side of the transformer to a lower voltage on the secondary side of the transformer. The common household voltage throughout North America is 120/240 volts obtained from the secondary windings of the step down utility owned transformer.
Where in the x-ray circuit is the timer located?
On the primary side of the high voltage transformer.
How do you calculate input voltage of a transformer given both side high and low side impedances and also load with power factor?
The input voltage (primary) and output (secondary) of a transformer is determined by the manufacturer. Transformers are bought to accommodate the voltage that is needed on the primary side and to what voltage is needed on the secondary side.
What changes a low voltage into a higher voltage?
The step up transformer is used to change the voltage from high to low or low to high voltage by eitherincreasing the number of inding or reducing the number of winding in the transformer,thus when the winding reduced on side of primary winding and ingreasing number of winding on secondary side it means the transformer should be step up transfo0rmer,and when the you increase number of turnsin primary side and reduce turned on secondary sidde the transformer said to be step down transformer
Why instruments are connected on low voltage side of the transformer while performing no load test?
since we need to get desired or rated voltage, so if it is connected in high voltage side of the transformer, voltage supply will be more, and hence the current will be more than the required amount. this is the reason why the instruments re connected at the low voltage of the transformer while performing no load test.
What happens to the current as the voltage is increased by the step up transformer?
Compare a transformer to a balancing act. Both side need to remain equal.The primary side of the transformer is the supply side and the load is connected to the secondary side of the transformer.The load governs the current of the secondary side of the transformer and the voltage of the secondary side must match the voltage that the load required to operate.The ratio of the transformer will determine what the voltage of the secondary side is as compared to the voltage that has to be applied to the primary.The current of a step up transformer will be higher on the primary side that that of the secondary.Apply voltage and current to this concept and you will see that the transformer will remain balanced.The size of the transformer is always calculated from the secondary side of the transformer and the value is written in VA or KVA where V = voltage and A = amperage. Power factor is also taken into consideration when calculating the size of the transformer to be used.
