We have met many customers , they choose the transformers according to pass experience or peer’s opinion, but they have no idea how to choose a transformers not to mention design. As a result they would be choose wrong transformers, mostly those transformers work smoothly but not the most effective setting as we concern. As to provide a suitable settings for your machine system, today we are going to talk about: How to choose a transformer? How to determine the reasonable capacity of the transformer?
First, we have to investigate the power supply voltage of the electricity consumption place,the real on load voltage of user and the conditions of the place, then choose the transformer according to the parameter marked on the brand. Generally, the transformer capacity, voltage, current and environmental conditions should be considered comprehensively. The transformer capacity should be selected according to the capacity, nature and usage time of the user's electrical equipment to determine the required load.
During normal operation, the electrical load that the transformer bears should be about 75 to 90% of the rated capacity of the transformer.When the actual load of the transformer is actually measured to be less than 50% during operation, the small-capacity transformer should be replaced. If it exceeds the rated capacity of the transformer, the large transformer should be replaced immediately.
At the same time, when selecting the transformer, the voltage value of the primary coil of the transformer is determined according to the line power supply, and the voltage value of the secondary coil is selected according to the electrical equipment. It is best to select the low-voltage three-phase four-wire power supply. This can provide both power and lighting.
For the selection of current, it should be noted that the load can meet the requirements of the motor when the motor is started (because the motor starting current is 4 to 7 times greater than when it is sinking).
If you still worry about choosing an unsuitable transformer, don’t worry, ECKO’s professional engineers with 20 years experience are here to serve for you ,we will design the transformers according to your requirement and give our suggestions about the problems happened in your system as we can do.
