How to choose the right voltage transformer

Date:2023-08-18

Rated voltage: Select the appropriate rated voltage according to the actual application scenario and the measured voltage range. The rated voltage of the transformer should be greater than or equal to the maximum value of the measured voltage, but generally should not exceed 110% of the rated current.

Rated current: Select the appropriate rated current according to the actual application scenario and the measured current range. The rated current of the transformer should be greater than or equal to the maximum value of the measured current, but generally should not exceed 110% of the rated voltage.

Accuracy level: Select the appropriate accuracy level according to actual needs. Generally, there are 0.1, 0.2, and 0.5 levels to choose from. The higher the accuracy level, the more accurate the measurement results, but the cost also increases accordingly.

Output signal type: Select the appropriate output signal type according to system requirements. Common output signal types include analog signals (such as current or voltage), digital signals, or communication interfaces (such as RS485, Modbus, etc.). Select the appropriate output signal type according to system requirements and compatibility with other devices.

Frequency response and bandwidth: Select the frequency response and bandwidth of the transformer according to the actual application scenario. If you need to measure high-frequency signals, you need to select a transformer with higher frequency response and bandwidth.

Rated load: Select the appropriate rated load according to the load characteristics of the circuit under test. The rated load of the transformer should be greater than or equal to the maximum load of the circuit under test.

Size and installation method: Select the appropriate size and installation method according to the actual installation space and requirements, such as fixed type, open hole type or plug-in type, etc.

At the same time, when selecting a voltage transformer, you should also pay attention to the following points:

Consider the reliability and maintainability of the transformer, and choose a well-known brand and a reliable supplier.

In short, choosing the right voltage transformer requires comprehensive consideration of the actual application requirements and technical parameters to ensure that it can meet the system requirements and provide accurate and reliable measurement results.
