What is the procedure to measure the magnetizing current in transformer?
i also do know the answer
How do you size wire for a step down transformer?
You size it by the current required by the secondary, and the primary will be smaller wire.
What are the factors affect the magnitizing inrush current in power transformer?
1- residual flux existing before enegizing the transformer . 2- size of transformer . 3- size of power system. 4- type of magnetic material of the core. 5- the method of energizing the transformer.
What is the cable size of 1600kVA transformer?
Cable size is determined by current. You did not provide the current, nor did you include the voltage so that we could calculate the current. Please restate the question, and include either the current or the voltage.
How do you calculate current on the primary side of a transformer only knowing the turns ratio and the voltage ratio?
The primary current on a loaded transformer depends on the secondary current, which is determined by the load. So, if you know the secondary load current, then you can use the turns ratio of the transformer to determine the primary current:Ip/Is = Ns/Np
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
What is principle of Current transformer?
why does have to short-circuit secondary wire of current transformer ?
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.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
How transformer get burn?
Current overload from whatever circuit draws current from the transformer? Proper fusing of its supply might protect a transformer from this cause. Or it could have developed a shorted turn fault because the insulation on a winding got old and perished? Or maybe the transformer got damaged if the appliance it is mounted in was dropped?
What is the secondary amps of 315kva transformer?
The secondary current is determined by the load, not by the transformer. But the load current mustn't continuously exceed the rated current of the secondary winding. To determine the secondary rated current, you need to know the rated secondary voltage of the transformer, and divide 315 kV.A by this figure.Incidentally, the correct symbol for 'kilovolt ampere' is 'kV.A', not 'kva'.
What is zero current transformer?
It is a transformer with No load attach to it.
