Main requirements and safety systems for precision current transformers

- Feb 28, 2019-

When the precision current transformer is in use, the protection current transformer mainly cooperates with the relay device. When the line is short-circuit overloaded, etc., when the operation is performed, the relay device is provided with a signal to cut off the fault circuit, so that the power supply system can be protected. Security. Current transformer for protection current transformer and current transformer for current protection for measurement.

The precision current transformer only starts to work effectively when it is several times larger than the normal current. The main requirements of the protection transformer are:

1. Insulation is reliable.

2. A sufficiently large accuracy limit factor.

3. Adequate thermal stability and dynamic stability.www.ctsensorducer.com
