Technical parameters and requirements

1、 Requirements for measuring transformers

（1） Current Transformer (CT)

Requirements for CT for overcurrent protection

Accuracy level and accuracy limit coefficient: The accuracy level of current transformers used for protection is usually represented by “P” (meaning protection), followed by the number indicating the maximum allowable composite error at the rated accuracy limit current. For example, 5P10 represents an accuracy level of 5P and an accuracy limit coefficient of 10. Both 5P and 10P levels are suitable for non directional overcurrent protection, with 5P level having higher accuracy.

Actual accuracy limit coefficient calculation: The actual accuracy limit coefficient (F a) is related to the rated accuracy limit coefficient (F n), CT rated load (S n), CT internal secondary load (S in), and actual external load (S). The calculation formula is:

F a ≈ F n × ∣ S n+S ∣∣ S in+S n ∣ CT selection principle: For non directional overcurrent protection, it is recommended to choose a CT with an actual accuracy limit factor of at least 20. The rated primary current (I 1n) of the CT should meet the requirement of I 1n>I kmax/100 (I kmax is the maximum fault current) to avoid exceeding the thermal and dynamic intensity of the input current measurement of the protective relay.

Suggestion for starting current setting: If I kmin is the lowest current that should be activated during the highest set overcurrent stage, the starting current should be set to:

The current starting value, with a coefficient of 0.7, takes into account protection relay error, CT error, and short-circuit calculation deviation.
