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.

8、电压互感器详细参数（型号、电压等级、变比、绕组数、精度、容量。注意事项：电压互感器外壳（铁壳）和二次侧必须同时接地，以降低高压窜入低压造成的危险性；电压互感器的一二次绕组都应接熔断器，以防止二次侧工作时接地和短路；电压互感器的二次回路连接导线应用绝缘软铜线，截面不得小于1.5mm2，不得使用铝导线；电压互感器二次回路的电压降不应超过0.5%，对0.5级电能表不得超过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.
