Load Requirements: Determine the type, size, and duration of the load the transformer will need to carry. Select the appropriate transformer capacity based on the stability and volatility of the load.
Voltage Requirements: Determine the input and output voltage ratings, range, and accuracy requirements. When selecting a transformer, ensure its output voltage meets the voltage requirements of the load equipment.
Environmental Conditions: Consider the environmental conditions of the transformer's installation location, such as temperature, humidity, and altitude. Select the appropriate insulation and protection levels based on the actual environment.
Efficiency Requirements: Consider the transformer's energy efficiency. Choosing a high-efficiency transformer helps save energy and reduce operating costs.
Safety: Consider the transformer's safety features, such as overload protection, short-circuit protection, and temperature protection, to ensure the safety of equipment and personnel.
