Overview of High-Voltage Current Transformer
High-voltage current transformers (CTs) are essential instrument transformers used in electrical power systems to measure and monitor high currents safely. They convert high current levels in transmission lines into proportional low current signals that can be used by meters, protection relays, and monitoring equipment.
These transformers are widely used in power plants, electrical substations, and high-voltage transmission networks, ensuring accurate current measurement and reliable protection of power system equipment.
How High-Voltage Current Transformers Work
High-voltage current transformers operate based on 電磁誘導, converting large primary currents into smaller, standardized secondary currents.
| 成分 | 関数 |
|---|---|
| Primary Conductor | Carries the high current from the power system |
| Magnetic Core | Transfers magnetic flux efficiently |
| 二次巻線 | Produces reduced current for measurement |
| 断熱システム | Ensures safe operation in high voltage environments |
| Protective Housing | Protects internal components |
The typical secondary current output is 1A or 5A, which can be safely measured by monitoring devices.
