6. Detailed parameters of current transformer (model, voltage class, transformation ratio, number of windings, accuracy and capacity). Precautions: the shell (iron shell) of current transformer and secondary side must be grounded at the same time; The secondary side of current transformer shall not be connected with knife switch and fuse; The secondary circuit connecting conductor of current transformer shall be insulated flexible copper wire, with the section not less than 1.5mm2, and aluminum conductor shall not be used; The load of secondary circuit of current transformer shall not be greater than the corresponding rated value with certain accuracy; The secondary side of current transformer in operation shall not be open circuit.)

7、熔斷器詳細參數（RN2熔斷器不能作過載保護，如需要對電壓互感順過載加以保護時，則可在電壓互感器的低壓側裝置低壓熔斷器。如果要使用于短路容量大于2000兆伏安的線路上時，則應在熔斷器前串聯限流電壓。標準參數：額定電壓(KV)、額定電流(A)、額定開斷容量(MVA,RN1<200\RN2<1000)）

7. Detailed parameters of fuse (RN2 fuse cannot be used for overload protection. If it is necessary to protect the voltage transformer from overload, a low-voltage fuse can be installed on the low-voltage side of the voltage transformer. If it is to be used on lines with a short circuit capacity greater than 2000 MVA, the current limiting voltage should be connected in series in front of the fuse. Standard parameters: rated voltage (KV), rated current (A), rated breaking capacity (MVA, RN1<200  RN2<1000))

8、電壓互感器詳細參數（型號、電壓等級、變比、繞組數、精度、容量。注意事項：電壓互感器外殼（鐵殼）和二次側必須同時接地，以降低高壓竄入低壓造成的危險性；電壓互感器的一二次繞組都應接熔斷器，以防止二次側工作時接地和短路；電壓互感器的二次回路連接導線應用絕緣軟銅線，截面不得小于1.5mm2，不得使用鋁導線；電壓互感器二次回路的電壓降不應超過0.5%，對0.5級電能表不得超過0.25%。）等等。

8. Detailed parameters of voltage transformer (model, voltage grade, transformation ratio, number of windings, accuracy and capacity). Precautions: the shell (iron shell) and secondary side of voltage transformer must be grounded at the same time to reduce the risk caused by high-voltage channeling into low-voltage; The primary and secondary windings of the voltage transformer shall be connected with fuses to prevent grounding and short circuit when the secondary side is working; The secondary circuit connecting wire of voltage transformer shall be insulated flexible copper wire, with the section not less than 1.5mm2, and aluminum wire shall not be used; The voltage drop of the secondary circuit of the voltage transformer shall not exceed 0.5%, and it shall not exceed 0.25% for the class 0.5 electric energy meter.) wait.
