Here is a professional PDX LV Power Distribution Box Factory talking about how to determine the reasonable capacity of the transformer.
We all know that in order to properly use power transformers, we must figure out some details of the power transformers. Only when we know what we know and know why, can we be targeted.
As a professional factory who has Strong Versatility Power Distribution Box, let's take a look at how to determine the reasonable capacity of the transformer:
First of all, it is necessary to investigate the power supply voltage of the electricity place, the actual power load of the user and the conditions of the place, and then select one by one according to the technical data indicated on the nameplate of the transformer. Generally, the capacity, voltage, current and environmental conditions of the transformer should be considered comprehensively. The transformer capacity should be selected based on the capacity, nature, and time of use of the user's electrical equipment to determine the amount of load required.
In normal operation, the load on the transformer should be about 75 to 90% of the rated capacity of the transformer. When the actual load of the transformer is less than 50%, the small-capacity transformer should be replaced. If it is greater than the rated capacity of the transformer, the large transformer should be replaced immediately.
At the same time, in selecting the transformer to determine the primary coil voltage value of the transformer according to the line power, and selecting the voltage value of the secondary coil according to the electric equipment, it is preferably selected as the low-voltage three-phase four-wire power supply. This provides both power and lighting power.
For the choice of current, pay attention to the load can meet the requirements of the motor when the motor starts (because the motor starting current is 4 to 7 times larger than the sinking operation).
