The open-close current transformer is an important power measurement equipment, which is widely used in various fields of power system. In order to ensure its normal operation and measurement accuracy, the following principles should be followed when using open-close current transformers:

1. Installation Specification

The installation shall follow the manufacturer's specifications and recommendations to ensure that the current transformer is correctly and securely installed on the busbar. At the same time, ensure good contact between the transformer and the bus to avoid current measurement errors or equipment damage due to poor contact.

2. correct wiring

Ensure that the current transformer is wired correctly to avoid damage to equipment or safety hazards due to incorrect wiring. At the same time, attention should be paid to check the open state of the secondary circuit to avoid secondary open circuit accidents.

3. overload protection

In practical applications, current transformer overload operation should be avoided as much as possible. If the actual current exceeds the rated current, it may result in increased current transformer error or equipment damage. Therefore, when selecting and using current transformers, the appropriate rated capacity should be selected according to the actual load current.

4. regular maintenance

Regularly check and maintain the current transformer, including checking whether the wiring is loose, checking whether the appearance of the equipment is intact, etc. If any abnormality is found, it should be handled and recorded in time to ensure the normal operation of the current transformer.

5. safe operation

When operating the current transformer, the safe operation procedures shall be followed to avoid electric shock accidents. At the same time, attention should be paid to protect the current transformer from external damage, such as to avoid collision, to prevent water, etc.

6. accurate calibration

To ensure the accuracy of the measurement, the current transformers shall be calibrated periodically. During the calibration process, relevant standards and specifications should be followed to ensure the accuracy of the calibration results.

7. reasonable selection

When selecting a current transformer, the appropriate model and specification should be selected according to actual needs. Improper selection may lead to increased measurement error or can not meet the actual needs.

In short, following the above principles to use the open-close current transformer can ensure its normal operation, improve measurement accuracy, and extend its service life. At the same time, during use, attention should also be paid to safe operation and standardized use to avoid equipment damage or safety hazards due to improper operation.
