In order to design a BCT with high accuracy, a primary with larger Ampere-turn is selected to achieve the demand. However, since the primary on the BCT is fixed only one turn, the higher accuracy of current ratio cannot be achieved easily for very small current occurred on the power transformer.

然因套管型比流器其一次安匝是固定的，当遇有一次次电流甚小时，因无法增加一次匝数以提高一次安匝，故难以实现较高的准确级。

It is impractical in laboratory calibration with this infinite single wire which can be replaced by an N-turn coil. According to the equal ampere-turn principle, it is feasible to calibrate the high current range of the clamp ammeters with low current. However, the calibration coil brings new uncertainty into the calibration.

根据等安匝原理，实验室常用多匝校验线圈代替单根导线对钳型表进行校准，如此只需小电流即可对钳形表大电流量程进行校准，但是校验线圈这种校准方法会引入新的测量不确定度。

At equilibrium,the rate of the metal dissolution is equal to the rate of the cathodic reaction,and the rate of the reaction is directly proportional to the current density by Faradar's law ;therefore:（6）and the Nernst equation can be rewritten(7)where B is a constant and i0 is the exchange current density,which is defined as the anodiccurrent density at the standard electrode potential.
