Current transformers are electrical devices used to measure alternating current (AC) in power systems. They work by producing a reduced current proportional to the current in the primary circuit, allowing for safe and accurate monitoring of high current levels. Typically made from high-quality magnetic materials, these transformers are essential for protecting equipment and ensuring accurate metering in electrical installations.
| Primary current rating | Up to several thousand amperes |
| Secondary current rating | Typically 5A or 1A |
| Accuracy class | Class 0.5 to Class 1.0 |
| Frequency range | 50Hz to 60Hz |
| Insulation class | Class A to Class F |
When selecting a current transformer, consider the primary and secondary current ratings to ensure compatibility with your system. It's important to specify the accuracy class required for your application, as this affects measurement precision. Additionally, check the insulation class for suitability in your operating environment, and confirm any necessary certifications for safety and compliance. Quantities may vary based on project needs, so be prepared to provide this information when requesting a quote.
