What are the troubleshooting methods for current transformers?
As a front - line fault maintenance worker, I deal with current transformers (CTs) daily. A CT’s secondary winding in operation must never open - circuit! Once open - circuited, the secondary current and demagnetizing potential vanish. All primary - side magnetic potential then becomes the iron core’s exciting potential, sharply increasing its magnetic flux density. High voltage on the secondary side will endanger safety anytime.Despite strict power operation regulations, user electr

What are the causes of current transformer faults and the countermeasures for faults?
What are the causes of current transformer faults and the countermeasures for faults?
As a front - line maintenance technician, I deal with current transformers (CTs) daily. CTs convert high - magnitude primary current to low - magnitude secondary current for substation/line protection and measurement, operating in series long - term. However, they face faults from external (unbalanced loads, wrong wiring, etc.) and internal (insulation defects) issues. These faults, like secondary open - circuits or insulation breakdown, harm measurement accuracy, protection operation, and grid
