摘要（英）：

The utility model discloses an electronic transformer interference signal test system in a GIS (Geographic Information System) based on a high-speed sampling. The system comprises a preposition acquisition module, a master control reception module and a host computer. The preposition acquisition module is arranged at a secondary side of the electronic transformer; the preposition acquisition module comprises a high-speed sampling AD conversion module and an FPGA sampling data transmission module; the high-speed sampling AD conversion module converts a collected current signal into a digital signal; the master control reception module comprises an FPGA sampling data reception module and a master control CPU; the FPGA sampling data reception module is connected with the FPGA sampling data transmission module of the preposition acquisition module; the FPGA sampling data reception module transmits received sampling data to the master control CPU; the master control CPU is connected with the host computer; and the host computer displays data results. The electronic transformer interference signal test system is quick in the sampling speed and high in the test precision.
