Some problems in transformer capacity calculation

1. The rated capacity of the transformer should be the large load that can ensure the normal operation of the transformer under the required application standards.

2, this apparent power is the power of the transformer, but also the transformer can carry a large load of apparent power.

3. When the transformer is running, the output power of the transformer is deemed to be equal to the rated capacity.

4. When the transformer is running at the rated value, the transformer's input power shall be deemed to exceed the rated capacity.

5, because the efficiency of the transformer is very high, it is generally felt that when the transformer is running at the rated value, the transformer's input power is equal to the rated capacity, so as to carry out the operation and the results are also based on accurate.

6, so in the application of the transformer, if you look at the transformer output current, working voltage, power factor and as if the power is equal to or lower than the rated capacity is safe (application standard consideration).

7, many people think that the transformer has loss, be sure to run in the rated capacity of 90* below is not correct!

8, transformer in the design of the volume, according to the calculation of the load multiplied by the performance of the safety * is right.
