The ground resistance measuring instrument is a new type of ground resistance measuring instrument which combines the three-end button and four-end button measuring methods by using advanced medium and large scale integrated circuit instead of the traditional manual manual power generation.
The working principle is that the DC/AC converter in the machine changes DC into low-frequency constant current of AC and the circuit is formed by auxiliary ground electrode C and measured ob
The earth resistance measuring instrument is suitable for measuring the earth resistance of various devices and the conductor resistance value of low resistance in electric power post and telecommunication railway communication mining and other departments. The table also measures soil resistivity and ground voltage.
