Product Description
Hengfeng ground resistance tester is a high-precision test instrument used in various fields such as substations for testing grounding resistance and related parameters.
The instrument has the characteristics of lightweight, small dimensions, convenient carrying, strong anti-interference performance and high accuracy. It is an integrated structure, built-in variable frequency power supply module, and the output power supply is continuously variable frequency adjustable. The frequency of 45-55Hz can be switched for measurement, and there are several groups of double frequency conversion for choice,and the built-in high-speed processor core adopts high-end digital filtering technology, which effectively avoids the interference of the power frequency electric field to the test, and fundamentally solves the problem of accurate measurement under strong electric field interference.
A large number of on-site tests and user usage indicate that when the grounding grid is tested under the harsh electromagnetic environment of the running substation, the measured data of the grounding impedance tester of the special frequency ground network are accurate and repeatable. It is an ideal instrument for the measurement of the characteristic parameters of large and medium grounding grids.
Ground Resistance Tester Features
1. HD color touch screen. The instrument is equipped with a high-end full-touch liquid crystal display, a large and full graphical operation interface, each process is very clear, and the operator can use it without additional professional training. The entire process can be measured with a single touch, making it an ideal smart measurement device.
2. Spare stylus pen. When the operators have dirt on their hands or dirt on the screen, the stylus pen can be used to operate the instrument.
3. Double frequency conversion,strong anti-interference ability. The instrument adopts the method of different frequency measurement, and with modern software and hardware filtering technology, the instrument has high anti-interference performance, and the test data is stable and reliable.
4. The precision of measurement is high. The basic error is only 0.005 Ω, which can be used to measure the earth network with very small earth impedance.
5. Powerful function. It can measure current stake, voltage stake, grounding grid impedance, grounding resistance, grounding conduction, soil resistivity, step voltage, touch voltage, potential gradient and so on.
6. Transmission tower vector shunt function.The instrument automatically subtracts the current that is transferred by the tower to calculate more accurate test results.
7. Built-in 1500 Ω imitate human body resistance, when testing step voltage ,users can get the real step voltage data and curve.(optional)
8. All English menu, easy to operate.
9. Simple wiring ,no high current cable is needed.
