Installation of substations
Thread Content
I’m not majoring in electrical engineering, and I have a question: 1. What voltage rating should the substations in a factory facility have? Is it determined by the voltage of the largest electrical equipment in the facility, or by the total electrical load? 2. Are there any recommended standards, books, or documents? Please provide one to help me get up to speed
Is it the capacity of the transformer? It is calculated by multiplying the rated voltage by the rated current, then adding those values together, and finally multiplying the result by a factor of 1.2 to 1.5. After obtaining this figure, it’s advisable to consult an electrical engineer to see if it is reasonable
Are you asking about the voltage in kVA and the capacity of the substation? It is determined based on the maximum kW value operating simultaneously, then divided by 0.9, with a certain margin left over. This should be designed by a design institute, right: lol
