It is connected, the measurement host enclosure interior is provided with main control processor, display module, signal injection module and radio communication mold
Block A, display module, signal injection module and wireless communication module A are connected with main control processor respectively, the testing current dress
Put including controller and current sampling device, current sampling device includes flexible current coil, amplifier module and channel radio
News module B, the flexible current coil, amplifier module and wireless communication module B are sequentially connected.
In order to preferably use running indicator, the present invention is improved to be had, and the running indicator includes qualified lamp and non-qualified lamp.
In order to preferably use measurement host housing, the present invention is improved to be had, and handle is provided with the measurement host housing.
In order to preferably use flexible current coil, the present invention is improved to be had, and the length of the flexible current coil is two meters.
Beneficial effects of the present invention are：Of the invention novel in design, simple structure is effectively solved in conventional art and existed
Some problems, the system can exclude interference of the aerial earth wire to measurement result, directly using flexible line current circle e measurement technology
After connecting instrument Injection Signal, measure and judge whether measured steel tower is led in earth mat is hidden from the signal results for receiving
The situation of logical welding, solves the problems, such as hand excavation's column foot and destruction steel tower, and improve the safe operation of transmission tower.
