Why is a current transformer needed in a high voltage cabinet
Sep 06, 2023| 1. Reduce the cost of measurement and protection systems: In high-voltage systems, current transformers convert large currents into small current signals, allowing the use of smaller-sized, low-cost measurement and protection equipment. This not only reduces the system cost, but also improves the reliability of the equipment.
2. Safety considerations: The large current in the high-voltage cabinet has a high risk. By using current transformers, large currents in high-voltage systems can be converted into safe low-current signals, reducing safety risks to operators.
3. Provide accurate current data: Current transformers can provide accurate current measurement data, helping operation and maintenance personnel understand the operating status of the power grid, discover potential problems in a timely manner, and conduct reasonable scheduling and maintenance.
