Some friends do not know how to configure their own electrical equipment with the corresponding capacity of the transformer, the following Shanghai Yu Peng company to introduce you to the formal configuration!
If the capacity of the transformer is large, the "big horse car" will increase the loss of no-load, waste the power resources, increase the cost of manufacturing; the capacity is small, with no equipment, the transformer will burn out the transformer.
The power factor of the transformer is 0.8. For example, a transformer of 10kva can withstand 8KW of load equipment. So some friends seem to think that it is not enough to buy a 10KVA transformer for my 8KW equipment.
Although it can be used, but it is still running at full load. If it is running for a long time, the transformer will heat up, so it is necessary to enlarge some margins. On the basis of the 0.8 fold, another 0.8 fold, that is, the transformer of 10KVA.
Take 0.8=8KVA and then take 0.8=6.4KVA, 10kva transformer to carry 6.4kva equipment just right!
Example: My motor is 50KW, then the capacity of the transformer is: 50/0.8/0.8=78KVA
