Current Transformers Manufacturers

List Technical Parameters of “current transformers manufacturers”

Current Transformers (CTs) are used in instrument transformers to measure electrical currents. They are widely used in electrical power systems for their safety and efficiency. Current transformers manufacturers must consider several technical parameters when designing and manufacturing CTs to ensure that they meet the accuracy, voltage, frequency, and thermal requirements specified by customers.

One of the most important technical parameters of CTs is their ratio. The ratio is the relationship between the primary current and the secondary current in the transformer. The selection of a proper ratio depends on the rated primary current, the burden of the secondary circuit, and the required accuracy of the measurement. Current transformers can have ratios ranging from a few milliamperes to thousands of amperes.

Another important technical parameter is accuracy. The accuracy of CTs is usually specified as a percentage of the rated primary current. The accuracy can be affected by factors such as temperature, frequency, and external magnetic fields. Therefore, current transformers manufacturers must design their products with appropriate core materials, winding arrangements, and insulation systems to achieve high accuracy.

The frequency response of CTs is also an important technical parameter. The CT’s frequency response is typically specified as a bandpass or a frequency range over which the transformer can accurately measure current. The frequency response depends on the core material, winding geometry, and insulation system.

The voltage class is another technical parameter that must be considered by current transformers manufacturers. The voltage class determines the maximum primary voltage that the CT can withstand without breaking down or causing any safety hazards. High-voltage current transformers can withstand voltage ranges of up to several kilovolts.

Finally, the thermal rating of the CT is also a crucial technical parameter. The thermal rating determines the maximum temperature rise of the transformer under rated load conditions. The thermal rating depends on the ambient temperature conditions, cooling system, and insulation system.

In conclusion, current transformers manufacturers must consider several technical parameters when designing and manufacturing CTs to meet the specific requirements of their customers. The ratio, accuracy, frequency response, voltage class, and thermal rating are just a few of the many technical parameters that determine the performance and reliability of current transformers.
